De-Stijl-Diptychon-Porträt aus einem Foto

Create a complete vertical top-and-bottom diptych illustration, strictly split 1:1 into upper and lower zones, so the whole reads as a carefully designed diptych rather than a simple paste-up. The upper half is a refined extraction of the original photo's subject; the lower half is a De Stijl reconstruction. Upper half: Use the uploaded photo as the sole subject reference, automatically identifying the main person, cat, dog, or other common pet, focusing on extracting the subject itself and ignoring the dominance of buildings and complex environments. Preserve as much of the subject's most identifiable information as possible, including a person's facial proportions, hairstyle, clothing, and demeanor, or a pet's coat color, markings, build, and features. Moderately clean up and simplify the background; keep the subject complete and clear with a stable composition. Lower half: Transform the same subject into a complete illustration in the visual language of the De Stijl style. Core stylistic features: horizontal and vertical black lines, the primary colors red/yellow/blue, and white planes in an ordered arrangement. Overall principles: use clear geometric structure, flat planes, and ordered composition, controlling hierarchy and negative space. Use a single clear subject or one clear scene, a stable visual center, the subject complete and not cropped, the background moderately simplified with room to breathe; lines, color blocks, light and shade, materiality, and paper texture must all serve the same style, without mixing in unrelated styles. The subject's outline, pose, the major relationships of the clothing, and the negative space should be rationally incorporated into the ordered system of vertical-horizontal black lines and primary-color planes, forming a highly geometric, structured De Stijl translation. The image should feel natural, with a handmade quality and recognizable stylistic traits, avoiding the over-smoothness, meaningless detail buildup, and random decoration common to AI. Overall requirements: The upper and lower subjects must correspond strongly; the lower half should be recognizable at a glance as a De Stijl stylized reconstruction of the same subject as the upper half. Unless the theme explicitly requires it, do not generate text, logos, watermarks, borders, or UI, and do not make a multi-image collage.
