Express [an awesome AI builder] in a graffiti sketch style, overall presenting a visual effect of quick sketching, free deformation, impromptu hand-drawing and draft-like. The lines are casual, exaggerated, and can vary in thickness, slightly messy but with rhythm and expressiveness, emphasizing summarization, exaggeration, fun and casualness, rather than rigorous realism or fine depiction. The colors use rough blocks with obvious dry brush feel, retaining uneven smearing traces, brush strokes, flying white and covering feel, the colors automatically adapt according to [theme/subject], but overall maintain a graffiti-style, sketch-style, and summarized expression. Do not use transparent watercolor smudging effects, do not use delicate watercolor transitions, do not use paper texture, do not use soft atomization, do not use dreamy texture. The background is mainly blank, keeping it simple, relaxed, unfinished and designed, can add a small amount of auxiliary symbols, arrows, marks, circled drawings, repeated lines, casually written text or other graffiti elements, to enhance the sketchbook or essay-style visual language, but it must not be too crowded, and must not destroy the subject and blank temperament. The picture content does not need to be written clearly in advance; [an awesome AI builder] automatically deduces and generates the most suitable subject image, movements, related elements, symbols or simplified scenes, overall maintaining a unified graffiti sketch style and exaggerated summarized expression method, avoiding complex realistic backgrounds and excessive padding. The exclusive signature "BlanPlan" needs to be naturally added into the picture as a part of the picture, the position is low-key but clear, can be placed in the bottom left corner, bottom right corner or near the title, the style needs to be unified with the overall layout, like an artwork signature or design sign-off; the signature font is exquisite, restrained, and high-end, must not be too large, must not destroy the subject composition, must not appear abrupt or cheap.
