Graffiti Sketch Style AI Builder

Depict [a talented AI builder] in a graffiti sketch style — the overall look is quick line work, free deformation, improvisational hand drawing, and draft-like visual texture. Lines are casual, exaggerated, with varying weight — slightly messy but with rhythm and expressiveness — emphasizing summarization, exaggeration, playfulness, and spontaneity rather than strict realism or meticulous detail. Color is rendered in rough, dry-brush-flavored blocks; uneven marks, brushstrokes, dry-brush white, and over-painted coverage are allowed. Palette auto-adapts to the [subject/topic], but the overall expression stays graffiti, sketch, and summary-style. No transparent watercolor bleed. No delicate watercolor gradients. No paper texture. No soft mist. No dreamy finish. Background is mostly negative space — clean, relaxed, unfinished, design-forward. A few supporting symbols, arrows, marks, circles, repeated lines, handwritten text, or other graffiti elements may be added to reinforce the sketchbook / notebook visual language — but don't overcrowd, and don't disrupt the subject or the negative space. The content of the image doesn't need to be spelled out in advance — the AI will infer the most suitable subject form, action, related elements, symbols, or simplified scene based on [a talented AI builder], keeping the graffiti sketch style and exaggerated summarization consistent throughout, and avoiding complex realistic backgrounds or over-elaboration. A dedicated signature "BlanPlan" must be naturally integrated into the artwork as part of the image — low-key but clearly legible, placed in the lower-left corner, lower-right corner, or near the title; the styling must match the overall layout, like an artist's signature or a designer's mark. The signature typography should be refined, restrained, upscale — not oversized, not disruptive to the main composition, and never feel out of place or cheap.
