Transformation de photo en affiche éditoriale aquarelle

Please create each photo I upload into a separate, high-end designed poster - no multi-image collages, each photo output individually. Overall use a 3:4 vertical composition, with the upper and lower zones strictly 1:1 in height, each occupying 50% of the frame. The upper section retains the original photo, accurately preserving the subject's identity, mood, pose, spatial relationships, true texture, natural lighting, and original color atmosphere - only applying subtle high-end photographic color grading to give it the quality of fashion magazines, art publications, and exhibition photography. To fit the format, the sky, ground, or environmental background may be naturally extended, but the subject must not be stretched, distorted, or altered. The lower section extracts the most recognizable subject, silhouette, pose, and narrative relationships from the photo, reimagining them as light, naive, vintage hand-drawn editorial illustration. Do not mechanically replicate details - instead, re-express through simplified forms, moderately exaggerated proportions, symbolic features, and humorous visual metaphors, while keeping the original instantly recognizable. Blend modernist editorial illustration, Bauhaus graphic composition, children's picture books, naive art, and fashion sketching sensibilities - forms should be concise, contours slightly hesitant with handmade errors, and local features may be moderately amplified, giving the image a sense of story, fashion, and playfulness. The color palette is extracted from the photo above, using a soft, limited palette of high lightness and low-to-medium saturation, unified by analogous colors, with small areas of complementary color creating visual accents. Use mixed textures of watercolor, gouache, colored pencil, pastel, and dry brush, preserving paper grain, show-through, broken strokes, rough edges, slight dirt, and old print registration shifts. The background features generous negative space, with only loose light washes, partial hatching, or simple geometric elements supporting the subject - avoid complex scene stacking, realistic lighting, smooth vectors, 3D rendering, and over-refinement. Text is distilled from the photo's location, people, scene, or theme into a few English keywords, titles, numbers, or fitting phrases, continuing the hand-drawn editorial language of the lower section. The main title uses slightly naive, vintage hand-lettered art type, while auxiliary text uses restrained, gentle sans-serif or serif fonts - with slight misalignment, tilting, stretching, color overprinting, or old print registration shifts, making the text feel like a natural part of the illustration growing within the image, not a pasted-on typographic element. Overall use an off-white or light background with generous negative space, with the upper and lower images echoing each other through shared subject features, colors, poses, and visual symbols. The overall mood is relaxed, playful, vintage, gentle, smart, chic, humorous, romantic, and loose - with a touch of awkwardness and quirky confidence, like a carefully preserved page from an old fashion picture book meeting a modern art magazine.
