Graffiti Sketch AI Builder Style

Prompt

Express 【{argument name="主体" default="一个厉害的AI builder"}】 in a doodle sketch style, with the overall visual effect being rapid sketching, freeform distortion, improvisational hand-drawn lines, and a rough draft-like appearance. The lines should feel casual, exaggerated, and varied in thickness, somewhat messy yet rhythmic and expressive, emphasizing abstraction, exaggeration, playfulness, and spontaneity rather than rigorous realism or detailed rendering. The colors should use rough, dry-brush-like block shapes, preserving uneven smudges, brush marks, dry-brush texture, and layered coverage. The palette should automatically adapt to 【主题/主体】, while the overall expression remains doodle-like, sketch-like, and abstract. Do not use transparent watercolor blending, delicate watercolor transitions, paper texture, soft haziness, or dreamy effects. The background should mainly be left blank, keeping it simple, relaxed, unfinished, and design-oriented. A small amount of supporting symbols, arrows, marks, circles, repeated lines, casually written text, or other doodle elements may be added to enhance the sketchbook or notebook-like visual language, but it must not be too crowded or disrupt the subject and the sense of whitespace. The content of the image does not need to be specified in advance; let 【{argument name="主体" default="一个厉害的AI builder"}】 automatically infer and generate the most suitable subject form, actions, related elements, symbols, or simplified scene. The overall style should remain unified in a doodle sketch aesthetic with exaggerated, abstract expression, avoiding complex realistic backgrounds and excessive elaboration. The image must naturally include the exclusive signature "{argument name="签名" default="BlanPlan"}" as part of the composition, placed discreetly but clearly, such as in the lower left corner, lower right corner, or near the title. The style should be consistent with the overall layout, like an artwork signature or design mark; the signature font should be refined, restrained, and premium, not too large, not disrupting the subject composition, and not appearing abrupt or cheap.
