Minimalist Hand Drawn Image

[Subject/Theme] rendered as a graffiti sketch, with the most fitting figure, action and related elements auto-inferred

Top-of-mind quick-outline composition, mostly blank background, simple, relaxed and unfinished with design sense; optional auxiliary symbols, arrows, marks, circles, repeated lines and casual handwritten text, not crowded

Flat illustrative lighting, no soft atomization, no dreamy texture

Sketchbook or jotting-style blank backdrop, no paper texture, no complex realistic scene

Graffiti sketch style: casual exaggerated variable-thickness lines, slightly messy but rhythmic and expressive, generalized and playful, not realistic; rough dry-brush color blocks with uneven smears and dry-brush effects, no transparent watercolor blooming or delicate watercolor transitions

Refined restrained high-end signature 'voxcat' integrated subtly but clearly in a lower corner or near the title, matching the layout, not oversized or cheap
