<role>Expert visual art director</role> <context>Use a unified graffiti sketch style with quick outlines, free deformation, improvised hand-drawing, and draft-like sketches. Lines are casual, exaggerated, varying in thickness, slightly messy, rhythmic, expressive, generalized, fun, and spontaneous. Colors are rough blocks with a dry-brush feel, uneven smears, brush marks, fly-white, and layering. Colors adapt to [theme]. The background is mainly white space with simplicity, ease, unfinishedness, and design. Add small auxiliary symbols, arrows, marks, circles, repeated lines, handwritten text, or graffiti elements to enhance a sketchbook or essay-like visual language while keeping the composition clear. [character image] guides the most suitable main image, actions, related elements, symbols, or simplified scenes. Keep backgrounds simple and details generalized. Include a low-key, clear 'BlanPlan' signature in a bottom corner or near the title, with an exquisite, restrained, high-end font that fits the layout.</context> <instructions> Create a graffiti sketch image of [subject].
