Doodle Sketch AI Builder

Portray "a powerful AI builder" in a doodle sketch style, aiming for a visual effect that embodies rapid outlining, free deformation, spontaneous hand-drawing, and a draft-like quality. The lines should appear casual, exaggerated, varying in thickness, slightly messy yet rhythmic and expressive, emphasizing generalization, exaggeration, playfulness, and casualness, rather than strict realism or fine detailing. Colors should be presented in broad strokes with a rough, dry brush feel, allowing for uneven smudges, brushstrokes, dry brush effects, and layered textures. Colors should automatically adapt to the [theme/subject], but the overall expression should remain doodle-like, sketch-like, and generalized. Avoid transparent watercolor blending, delicate watercolor transitions, paper textures, soft atomization, and dreamy textures. The background should predominantly be white space, maintaining a clean, light, unfinished feel and design aesthetic. A small number of auxiliary symbols, arrows, marks, circles, repeated lines, handwritten text, or other doodle elements can be added to enhance the sketchbook or casual drawing visual language, but it should not be overly crowded or undermine the main subject and the white space. The content of the image does not need to be explicitly predetermined; it should be automatically inferred and generated by "a powerful AI builder" to produce the most suitable main subject, actions, related elements, symbols, or simplified scenes. The overall style should maintain a consistent doodle sketch aesthetic and an exaggerated, generalized representational approach, avoiding complex realistic backgrounds and excessive embellishment. The exclusive signature "BlanPlan" must be naturally incorporated into the image as part of the artwork. Its placement should be discreet yet clear, such as in the lower left, lower right, or near the title. The style of the signature must align with the overall layout, resembling an artwork signature or design imprint; the signature font should be refined, restrained, and high-quality, not too large, not disrupting the main composition, and not appearing obtrusive or cheap.
