| Position | Design name | Niche | Artwork description | Wording | Style | Color palette |
|---|---|---|---|---|---|---|
| sensenmann-einhorn-death-metal | SLOGAN | A cartoon Grim Reaper — a grinning skull and rib cage inside a windblown dark blue-gray hooded robe — rides a cream unicorn with a golden spiral horn, pastel rainbow mane, and long rainbow tail while swinging a scythe overhead. The unicorn jumps over a pastel rainbow with pink reins; puffy cream clouds, four small cream ghosts, white four-point sparkles, and scattered colorful dots surround it, all covered in a grainy speckle texture. One word sits above the scene and the other below it, both in very large soft coral-pink retro bubble capitals as wide as the illustration. Playful pastel palette of coral pink, turquoise, peach orange, cream, gold, and dark blue. No frames, ornaments, background panels, or additional text. Use solid letterforms without outlines or borders. | DEATH METAL | retro cartoon illustration, groovy bubble display type, pastel rainbow, grain texture, cute goth | coral pink, turquoise, peach orange, cream, gold, dark blue | |
| gans-liegestuhl-stay-weird | MOTIF | A white cartoon goose with an orange beak and large orange webbed feet lounges in a red-and-white striped wooden deck chair on the sand. It wears black aviator sunglasses, a white headband, and an olive checked scarf while raising a glass of red wine. A warm-yellow sun, small white seagulls, calm water drawn with a few cream wave lines, and a sandy mound with grasses and pebbles complete the scene. Use thick black cartoon contours and flat colors. Set the first line in an arch above the head and the second large along the bottom, both in very bold, softly rounded solid-white capitals without outlines. Warm beach palette of sand beige, sunny yellow, signal red, and olive green on a black-and-white base. No frames, ornaments, background panels, or additional text. | STAY WEIRD STAY WONDERFUL | bold cartoon mascot, thick black outline, flat color illustration, rounded display caps, beach vacation humor | white, black, sand beige, sunny yellow, orange, signal red, olive green, wine red | |
| passionate-snake-rose | URBAN | A photorealistic portrait composition of a slender snake looping around a thorny rose stem, its head raised at the upper left and forked tongue reaching toward the fully opened flower. The scales shift from olive green through copper and crimson to charcoal. A half-open bud, large dark-green leaves with water droplets, and sharp red thorns surround it. Above, set the main word very large in a white highly condensed high-contrast serif, lightly arched and partly overlapped by the bloom and snake head. Add three centered, widely tracked white capital lines below in a smaller serif. Crimson and copper contrast with dark leaf green; typography is pure white. No ornaments, frames, background shapes, or outlined lettering. | PASSIONATE PASSIONATE SOUL CAPTURES THE ESSENCE OF AN INDIVIDUAL DRIVEN BY INTENSE FEELINGS AND STRONG EMOTIONS. | photorealistic illustration, snake coiled around rose, botanical detail, condensed white display serif, dark romantic streetwear | crimson to rose red flowers, copper-red and olive-green scales, dark leaf green, white typography | |
| kind-of-a-big-dill-gurkenglas | SLOGAN | Center a tightly filled preserving jar with a ribbed warm-brass lid. Inside, closely packed pickles in several green and mustard-yellow shades show distinct bumps, with delicate dill sprigs, two garlic cloves, black peppercorns, and small air bubbles between them. Give the glass bright highlights and a thick black contour. Set one gently arched line above the jar in thick solid-white marker capitals without an outline, and a second, much larger line below across the full width. Palette: pickle green, mustard yellow, and brass. No ornaments, frames, background shapes, or outlined lettering. | KIND OF A BIG DILL | sticker illustration, thick black outline, hand-drawn marker caps, glossy jar rendering, food humor | pickle green and olive green, mustard yellow, brass gold, cream white, black contours | |
| schwarze-katze-rote-sonne | MOTIF | A black long-haired cat sits upright in profile with its head turned left, one bright eye visible, and its long bushy tail curling forward. Behind it is a large red sun disc with frayed horizontal brush edges. Glowing red ink drawings are embedded in the black fur: a large Japanese character on the chest, a broad spiral across the hip, and swirling tendrils on the neck and back. A thin cherry-blossom branch enters from the left, individual blossoms and leaves drift through the air, and red ink ribbons sweep around the figure. Palette: deep black and signal red. No ornaments, frames, lettering, or background shapes beyond the sun disc. | japanese ink illustration, sumi-e brushwork, red sun disc, black silhouette, tattoo flash, cherry blossom accents | deep black, vivid signal red to vermilion, a few white highlights | ||
| first-strike-winged-archer | URBAN | The main motif is a flying archer inspired by antiquity: a muscular winged youth with curly hair strides through the air while drawing an acanthus-decorated bow and aiming an arrow to the right. Long bands of fabric stream around his arms and legs, and he wears strapped sandals. Render the whole figure as a finely hatched grayscale engraving with a silvery marble sheen. Behind it, place the main word in a very large, towering, extremely high-contrast serif in saturated violet, partly obscured by wings, bow, and garment. Repeat the statement small, white, and widely tracked between two thin lines across the top, plus a compact micro-type block at lower right. Palette: white and gray engraving with one rich violet. No extra ornaments, frames, background shapes, or outlined lettering. | STRIKE FIRST STRIKE INTERNAL FOCUS | engraved greyscale illustration, classical winged archer, marble rendering, high contrast didone serif, violet spot color, letterspaced micro type, editorial streetwear | white and silver gray for figure, wings, and garment, rich violet-purple for the large serif, white and gray micro type | |
| skelett-liegestuhl-only-one-beer | SLOGAN | At left, a cartoon skeleton lounges wide-legged in a red-and-white striped wooden deck chair. It wears mirrored sunset sunglasses, an open white Hawaiian shirt with turquoise, pink, and orange flowers, turquoise shorts, and turquoise slides; one hand rests behind its head while the other holds a full foaming beer mug. A curved palm tree, orange evening sun over turquoise water, tropical leaves, and a sandy strip sit behind it. At right, arrange the saying in a tall left-aligned stack with dramatic size changes: white bold capitals, orange-to-yellow emphasis words, a smaller bridge line, the quoted word with yellow sparkle rays and orange underline, a huge solid-white penultimate word, and an orange-yellow final word over a turquoise wave. Warm beach palette of orange, sunny yellow, turquoise, white, and sand beige. No frames, ornaments, background panels, or additional text. | I DON'T EVEN BELIEVE MYSELF WHEN I SAY "ONLY" ONE BEER. | cartoon skeleton illustration, tropical sunset scene, layered display lettering, gradient bold caps | orange, sunny yellow, turquoise, white, sand beige, red, black | |
| opossum-first-of-all-delight | MOTIF | A close frontal portrait of an opossum with its head slightly tilted and mouth wide open, showing sharp canines and a pink tongue. Its pink nose and inner ears are the only color accents. Build the long shaggy fur from fine radiating strokes and send long bright whiskers outward. Place broad black retro sunglasses with striped temples and bright reflection bands over its muzzle. Set one gently upward-curving line above the head and a second below the animal, both in tall narrow white serif capitals with a fine scratched texture. Black-and-white palette with one soft-pink accent. No ornaments, frames, background shapes, or outlined lettering. | FIRST OF ALL I'M A DELIGHT | detailed ink linework animal portrait, vintage condensed serif caps, spot color accent, high contrast | black and white, muted pale pink as the only color accent | |
| darkrose-blackletter-bouquet | URBAN | A dense frontal rose bouquet with three fully opened blooms and two buds on thorny stems. The flowers are deep blood red with nearly black centers, and individual blood drops run from buds, leaves, and thorns. Keep all foliage deliberately desaturated from silver gray to charcoal so only the blooms carry color. Arch the main word above the bouquet in large blackletter with pointed hooks and sword-like terminals, using solid white letters without outlines. Repeat the final word widely tracked at the bottom, overlapped by leaves and thorny vines, so the two lines bracket the motif. Add a small fine script line twice within the composition. Palette: blood red on silver gray with white typography. No frames, background shapes, extra ornaments, or outlined lettering. | DARKROSE The Richest ROSE | gothic blackletter headline, dark floral, deep red roses, desaturated silver foliage, blood drips, high detail apparel print | blood red to wine red for blooms and drops, silver gray to charcoal for leaves and stems, white |

Clear before your first run.
Credits, file formats, garment tones, and downloads are explained clearly before your first run.
FAQWhat does one credit include?
One credit is charged for one delivered output in one garment tone. Background removal and finalization happen before the preview. Downloading costs no additional credit.
How long are credits valid?
Plan credits remain valid until the end of each monthly allocation window and do not roll over. Credit packs remain valid for 12 months from purchase and survive a plan change.
Do I download the artwork I see in review?
Yes. You download the finalized artwork as the transparent PNG file on which the reduced preview is based. Any visible garment stage is not part of the file. Downloading does not trigger new background removal.
Does downloading again cost credits?
No. While the file remains available in your download window or library, downloading it uses no additional credit. If your plan loses library access, existing library files remain downloadable for 30 days and are deleted afterward.
