It's written in a graffiti style (a powerful AI builder) that presents the visual effects of fast mapping, free deformation, improvisation and drafting. Lines are random, exaggerated, nuanced, slightly obfuscated, but pacified and expressive, with emphasis on generalization, exaggerating, interesting and random, rather than being written or crafted. Colours are presented in rough, dry-painted surfaces, which preserve an uneven sense of painting, brushing, whiteness and cover, and are automatically adapted according to [themes/subjects], but are expressed in a graffiti, abbreviated, general form. Don't be transparent about water colour dizziness, don't be obstinate, don't texture, don't be soft and fogged, don't be dreamy. The background is mainly white, keeping a simple, easy, incomplete and designer sense, with a small number of auxiliary symbols, arrows, markings, collages, repeat lines, handwritten text or other graffiti elements to enhance short-text or pen-style visual language, but not too crowded to destroy the body and white quality. The content of the image does not need to be pre-written, automatically inspired by [a great AI builder] and generated the most appropriate mass image, action, related elements, symbols or simplistic scenes, so as to maintain a uniform pattern of sketching and exaggerating, avoiding complex factual background and overlaying. It is natural to add an exclusive signature “BlanPlan” as part of the picture, which is low-key but clear and can be placed near the lower left corner, the lower right corner or the title, in a style that is consistent with the overall layout, as if the work was signed or designed; the signature is well-written, restrained, advanced, not too large, unbroken, non-intensible, non-intensible.
