Ilustración de Creador de IA en Boceto Grafiti

An expressive illustration of [a powerful AI builder] in a graffiti sketch art style. The character features quick improvised outlines, playful exaggerated deformation, and draft-like hand-drawn linework with varied thickness and rhythmic spontaneity. Rough color blocking with a distinct dry-brush feel, visible paint smears, and layered dry-ink textures tailored to the subject. The background is clean minimalist white space, creating an airy, unfinished sketchbook aesthetic. Subtle auxiliary draft symbols, small doodle arrows, circles, and faint scribbled notes are lightly scattered without cluttering the composition. An elegant, subtle artist signature reading "BlanPlan" is placed unobtrusively in a lower corner. Strict constraints: no realistic rendering, no soft watercolor blends, no complex realistic backgrounds, and no paper texture overlays.
