Cover Layout Design

Portray [an awesome AI builder] in a doodle-sketch style, with an overall look of quick strokes, free deformation, improvised hand drawing and draft-like rendering. The lines are casual, exaggerated, and may vary in thickness, slightly messy yet rhythmic and expressive, emphasizing abstraction, exaggeration, playfulness and spontaneity rather than rigorous realism or fine rendering. Color is applied in rough blocks with a pronounced dry-brush feel, keeping uneven smears, brush marks, dry-brush gaps and overpainting; the palette adapts automatically to [theme/subject], but the overall expression stays doodle-like, sketch-like and abstracted. No transparent watercolor bleeding, no delicate watercolor gradients, no paper texture, no soft haze, no dreamy finish. The background is mostly empty, kept simple, relaxed, unfinished and design-conscious; a few supporting symbols, arrows, marks, circled areas, repeated lines, casually written words or other doodle elements may be added to strengthen the sketchbook or notebook visual language, but it must not become crowded and must not spoil the subject or the airy negative space. The content of the picture does not need to be specified in advance: [an awesome AI builder] is worked out automatically to generate the most fitting subject, pose, related elements, symbols or simplified scene, keeping a unified doodle-sketch style and an exaggerated, abstracted manner throughout, avoiding complex realistic backgrounds and excessive elaboration. The dedicated signature "BlanPlan" must be worked naturally into the image as part of it, placed discreetly but legibly, in the lower left corner, lower right corner or near the title, in a style consistent with the overall layout, like an artist's signature or a designer's mark; the signature typeface is refined, restrained and elegant, not too large, not disruptive to the composition of the subject, and never abrupt or cheap-looking.
