Single Photo 3:4 Split Poster with Pastel Crayon Doodle AI Image Prompt

Make each uploaded photo into a separate high-end design poster; no multi-image collage, output each photo independently. Overall use a 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, preserving the subject's identity, structure, pose, realistic texture, natural lighting and original color atmosphere, with only subtle high-end color grading so it has the texture of art magazines, independent publications and exhibition imagery. To fit the aspect ratio, the environmental background may be naturally extended, but the subject must not be stretched, distorted or altered. The lower half first understands the original photo's most memorable core theme, subject relationships, structural direction, emotion and visual metaphor, then reconstructs it as a pastel crayon doodle illustration with vintage paper texture. Do not copy the photo object by object, and do not fully trace and redraw all content; retain only the contours, poses, directions and visual memory points that best represent the original objects, and through omission, simplification, slight exaggeration and recomposition, make the correspondence with the upper photo immediately perceptible. The subject uses coarse-grained chalk / crayon-style hand-drawn contours: lines slightly thick, loose, dry, with powder grains, broken fading, slight jitter and incompletely closed edges, and naturally blunt rounded stroke ends. Inside the subject, add only a very small amount of pastel color blocks, simple grids, stripes, dots or casual scribbles, using minimal information to hint at structure, without realistic volume or complete details. Surrounding small elements use the same line language as the subject, but are further compressed into doodle symbols recognizable in one or a few strokes. Stars, flowers, plants, objects, environmental clues or abstract symbols should all be simple, naive, open, incompletely closed, mainly single-line contours, with very little fill. Do not draw them as refined icons, stickers or separate small illustrations. The composition maintains the relationship of small-scale stamp and large areas of negative space, freely arranging positions according to the subject's own direction, proportion and visual center of gravity; it may be off-center, touch the edge, float suspended, or be partially cropped. The subject and a very small number of doodle symbols form a loose but clear visual cluster, while the rest of the space is actively left empty. Negative space itself is a main compositional element, creating a sense of breathing, distance and pause through empty and solid, gathering and scattering, size contrast and asymmetrical relationships; rather draw less than fill it up. The background must use a very light, bright, clean paper base color, such as cream white, ivory white, light rice white, pale apricot white, very light gray white, or a near-white paper color intelligently matched to the overall color temperature of the original image. The paper retains only very slight fibers and grain, and must not be brownish, yellowish, grayish or look aged. The background brightness must be clearly higher than the subject lines and color blocks, ensuring all crayon contours, small symbols and text are clearly visible and do not blur together with the background. The color palette extracts 2–4 of the most vivid, friendly and representationally spirited colors from the upper photo and re-mixes them, transforming them into bright, soft pastel crayon colors. They may naturally form light colors such as peach pink, apricot orange, cream yellow, mint cyan, sky blue, light purple; subject lines should preferably use coral pink, soft blue, teal green, warm orange, light purple or deep cream tones that are clearer than the background, while small elements only sporadically repeat these colors to create resonance. Overall maintain the contrast relationship of light background + clear colored lines + a small amount of soft color blocks, bright, healing, relaxed and life-like. Avoid darkness, dirty brown, dull Morandi-style desaturation, low contrast, fluorescent colors and cheap candy feel. Text intervenes in small amounts, with no language restriction. Freely distill short phrases or text fragments from the subject, action, emotion, memory or metaphor, using a thin, airy typewriter-style typography font with slight irregular letter spacing and old mechanical printing errors, in colors that are clear but not harsh: gray-brown, soft black, dark blue-gray, or deep colors echoing the subject, ensuring sufficient readability on the light paper. Text naturally scatters in the negative space, forming mixed image-text layout with the subject and doodles, without a fixed title template. Overall, present a high-end healing visual composed of an extremely light paper surface, coarse-grained crayon contours, a small amount of pastel fill, minimalist doodle symbols, small-scale subjects and abundant artistic negative space. The key is to make the subject and small elements clearly emerge on the light paper surface, while maintaining a relaxed, naive, gentle and mature editorial compositional awareness. Avoid dark kraft paper, dark brown backgrounds, low-contrast lines, background and subject blurring together, fine outlines, realistic redrawing, complex small icons, filled background, smooth vector, 3D feel and commercial template feel.
