Graffiti Sketch Style AI Builder

Prompt

Express【{argument name="主体" default="一个厉害的AI builder"}】in a doodle sketch style, with the overall visual effect of quick linework, freeform deformation, improvised hand drawing, and a sketch-like feel. The lines should feel casual, exaggerated, vary in thickness, and be slightly messy but rhythmic and expressive, emphasizing abstraction, exaggeration, playfulness, and spontaneity rather than strict realism or detailed depiction. Use rough, dry-brush-like blocky color areas, allowing uneven brush marks, brushstrokes, dry-brush streaks, and layering effects to remain visible. The colors should adapt automatically according to【{argument name="主题" default="一个厉害的AI builder"}】, but the overall expression should remain doodle-like, sketch-like, and abstract. Do not use transparent watercolor washes, delicate watercolor transitions, paper texture, soft misting, or dreamy textures. The background should mainly be left blank, staying simple, relaxed, unfinished, and design-oriented. A small amount of auxiliary symbols, arrows, marks, circles, repeated lines, casually written text, or other doodle elements may be added to enhance the sketchbook or note-like visual language, but it must not become too crowded or disrupt the sense of the subject and whitespace. The content of the image does not need to be specified in advance;【{argument name="主体形象" default="一个厉害的AI builder"}】should automatically infer and generate the most suitable subject form, pose, related elements, symbols, or simplified scene. The overall style should remain unified in a doodle sketch look with exaggerated, abstract expression, avoiding complex realistic backgrounds and excessive embellishment. The image must naturally include the exclusive signature “BlanPlan” as part of the composition, placed discreetly but clearly, and it may appear in the lower left corner, lower right corner, or near the title. The style should be consistent with the overall layout, like an artist’s signature or design credit; the signature lettering should be refined, restrained, and premium, not too large, not disturbing the subject composition, and not appearing abrupt or cheap.
