Illustrazione a Schizzo Graffiti Espressivo

A graffiti sketch illustration of [a powerful AI builder], rendered with an energetic, rapid sketchbook quality. Casual, expressive hand-drawn lines with exaggerated thickness, rhythmic messiness, and playful spontaneity rather than fine realism. Rough dry-brush color block fills with uneven smears, textured brush strokes, flying white gaps, and layered painterly patches, color palette naturally fitting the subject. Set against a clean, mostly white, unfinished design-oriented background with generous negative space. Accented with subtle sketchbook doodles such as small arrows, circles, scribbles, and handwritten notes without cluttering the composition. Discreetly signed with an elegant, refined artist signature reading "[BlanPlan]" in the corner.
