Illustration Graffiti Sketch Voxcat Signature

Create [Subject/Theme] in a graffiti sketch style, with the overall image feeling quickly outlined, freely distorted, spontaneously hand-drawn, and draft-like. The lines should look casual and exaggerated, with varied thickness; slightly messy, yet rhythmic and expressive. Emphasize simplification, exaggeration, playfulness, and spontaneity rather than strict realism or refined detail.

Use rough color blocks with a clear dry-brush quality. Uneven smears, brush marks, skipped dry-brush texture, and layered coverage may remain visible. The palette should adapt naturally to [Subject/Theme], while the overall treatment stays graffiti-like, sketch-like, and simplified. Avoid transparent watercolor blooms, delicate watercolor gradients, paper texture, soft misty diffusion, or dreamy effects.

Keep the background mostly blank, simple, relaxed, intentionally unfinished, and design-forward. Add a small number of supporting symbols, arrows, marks, circles, repeated lines, casually written notes, or other graffiti elements to strengthen the sketchbook or notebook-like visual language, but do not make the composition crowded or weaken the subject and the clean negative space.

The image content does not need to be specified in advance. Let [Subject/Theme] determine the most suitable subject form, pose, related elements, symbols, or simplified scene. Maintain a unified graffiti sketch style with exaggerated, simplified expression, avoiding complex realistic backgrounds or overdeveloped storytelling.

Naturally include the exclusive signature "voxcat" as part of the image. It should be subtle but clear, placed in the lower left, lower right, or near the title. Its style should match the overall layout, like an artist signature or design sign-off. The signature typography should feel refined, restrained, and premium; it must not be too large, disrupt the subject composition, or appear abrupt or cheap.
