Awesome AI builder

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. casual, exaggerated lines with varying 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, colors automatically adapt to the theme, 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, a small amount of auxiliary symbols, arrows, marks, circled drawings, repeated lines, casually written text, 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 bottom left corner, the style needs to be unified with the overall layout, like an artwork signature or design sign‑off; the signature font is exquisite, restrained, high‑end, must not be too large, must not destroy the subject composition, must not appear abrupt or cheap.
