Póster collage de doodles pastel a partir de tu foto

Please turn each photo I upload into a separate high-end design poster; no multi-image collages, each photo output individually. Use an overall 3:4 vertical composition, with the upper and lower areas strictly 1:1 in height, each occupying 50% of the frame. The upper half retains the original photo, keeping the subject's identity, structure, pose, real texture, natural light and shadow, and original color atmosphere, applying only slight high-end color grading to give it the quality of an art magazine, independent publication, and exhibition image. To fit the format, the environmental background may be naturally extended, but the subject must not be stretched, distorted, or altered. The lower half first understands the most memorable core theme, subject relationships, structural trends, emotional atmosphere, and visual metaphor of the original photo, then reconstructs them into a retro paper-textured pastel hand-drawn doodle illustration. The whole still maintains the logic of material collage, but do not fully copy the photo, nor transcribe object by object; instead, remove irrelevant details and keep only the most representative structure, trends, and visual memory points, re-summarizing them through hand-drawn doodles, paper collage, pastel crayon texture, naive shapes, and diary-style reorganization, so that after understanding and recreation, the correspondence with the photo above can still be recognized at a glance. The modeling uses a mixed-media logic of hand-drawn doodle + paper collage + pastel crayon texture. Lines are deliberately irregular, preserving a sense of sketch, hand-drawing, slight clumsiness, and looseness; color blocks have dry granular edges, like marks gently applied with crayon, chalk, or colored pencil. The subject and a few auxiliary elements can be recombined like stickers, paper scraps, or casually drawn symbols, but always around the subject's narrative, without meaningless piling up. The composition maintains the relationship of small-scale seals and large areas of white space, freely arranging positions according to the subject's own direction, proportion, and visual center of gravity, which may be off-center, edge-aligned, suspended, or partially cropped. The subject and a few auxiliary elements form a clear visual landing point, with the rest of the space actively left empty. The white space must be a conscious compositional language, not an empty background: together with the subject, collage elements, text, and local symbols, it forms positive and negative shapes, density, dispersion, and asymmetrical balance, creating a clear sense of breathing, space, and pause. Prefer to reduce rather than fill. The material is based on a paper texture like kraft paper, recycled paper, or handmade paper, preserving a real material feel and slight granularity, reducing the digital feel. The whole looks like an independently published diary, visual journal, or scrapbook editorial illustration, not an ordinary children's illustration or simple transcription. The color scheme extracts the 2–4 most lively, approachable colors that best represent the spirit of the photo above, remixing them into a softer, brighter, more healing pastel color group. It can naturally form light color relationships such as peach pink, light blue, cream yellow, orange-apricot, and tender green, moderately brightening, purifying, and de-graying, while keeping warm, intimate, retro, and life-like feel. Avoid dull, dirty, gloomy retro, fluorescent colors, and cheap candy feel. The text has only minimal editorial intervention, with no language restriction. A few words or short phrases can be freely extracted from the subject, location, action, emotion, life details, or metaphor, using a small, restrained, slightly mechanical and slightly misaligned retro typewriter-style font, forming a diary-style image-text collage relationship with the illustration, quietly landing in the white space area or the edge of the subject, without commercial title piling. The whole presents a high-end visual effect composed of hand-drawn doodles, material collage, pastel crayon, paper texture, small-scale seals, large areas of conscious white space, and retro image-text mixing. Avoid object-by-object transcription, filled frames, complex backgrounds, realistic depiction, smooth vectors, 3D feel, cheap cartoon feel, and templated collage.
