Photo instruction: 【写真】. Use the attached pet photo as the identity reference. Preserve species, head and ear silhouette, eye color, fur colors and especially the exact left/right positions and boundaries of distinctive markings. Simplify fur into bold carved flat ink shapes without recoloring or inventing patches. If several pets appear, use the largest foreground pet only. PHOTO RULE: when no photo is attached, invent one original cream-and-chocolate upright-eared mixed-breed dog with an asymmetric eye patch; finish without asking for a photo.
Background color: 【背景色】. Empty means tomato red. Use a single full-bleed solid color, separate from the pet's unchanged fur colors.
Expression: 【表情】. Empty means a smug half-closed gaze and crooked grin. Exaggerate eyes and mouth for warm visual humor while preserving the pet's identity and natural facial structure. Never add extra eyes, teeth rows or limbs.
If the attachment is a before/after comparison, use only the photographic panel as the identity reference and ignore the illustrated panel. Copy neither panel's expression: apply the requested expression instead. For a smug half-smile, use half-closed eyelids, a closed mouth with one corner raised, and no visible tongue. Preserve the photographic panel's original fur palette; do not adopt the illustrated panel's ink colors.
Use a large head-and-shoulders composition filling the frame, keeping both ears readable. Build broad graphic ink planes, confident cut contours and restrained uneven ink grain; no gradients, glossy 3D or photorealistic fur. Keep the same silkscreen medium for every expression. No accessories unless already essential to the subject, and remove all branding. Original animal character only; no existing characters, real brands, logos, signatures, watermarks, text, letters or numbers. No border, paper mockup or scene around the artwork.
