Minimalist collage art magazine poster prompt

Please create an individual high-end design poster for each photo I upload, not a multi-photo collage; each photo should be output separately. Use a 3:4 vertical composition overall, with the top and bottom sections strictly 1:1 in height, each occupying 50% of the frame.

The upper half retains the original photo, maintaining the subject's identity, structure, posture, realistic texture, natural lighting, and original color atmosphere, with only slight high-end color grading to give it the texture of an art magazine, independent publication, or exhibition image. To fit the aspect ratio, the environmental background may be extended naturally, but the subject must not be stretched, distorted, or changed.

The lower half adopts a **dual-layer paper and material collage texture**: the outer layer is an off-white, rough, handmade paper texture with coarse fibers. A **horizontal narrow rectangular collage color block area** is set in the middle of the frame, with casual, irregular edges, and the color is automatically matched to the photo above as a low-saturation but vibrant composite color. Do not copy the photo completely; instead, first understand the **structure, movement, visual memory points, and temperament** most worth remembering from the original image, delete irrelevant details, and retain only the core form and relationship that best represent the original object. Then re-summarize it through paper collage, layered color blocks, and hand-drawn lines, so that people can recognize its correspondence with the photo above at a glance.

The subject falls within the middle color block area with a **small-scale stamp feel**, and its position can be freely arranged according to its own direction, proportion, and visual focus, allowing for off-centering, edge-clinging, suspension, or partial cropping, without pursuing a complete representation. The composition must retain **a large amount of intentional white space**: leave ample blank space above and below the color blocks, letting the white space itself become part of the picture, creating a sense of breathing, space, and quiet editorial order together with the subject, the edges of the color blocks, and a small number of elements. Better to subtract than to fill.

The expression method is mainly **dark matte wax crayon / pastel-style hand-drawn lines**, with minimalist, loose, naive, casual, and irregular lines, with slightly rough brushstrokes and natural handmade errors; it can be supplemented with a small amount of etched lines, silhouettes, simple color blocks, and slight layering, without realistic redrawing or adding complex details. **Some key outlines, etched lines, or local details can be added with thin gold thread / gold powder lines**, like faint gold leaf powder attached to the edges of the lines, forming a restrained and exquisite sense of flash, just enough without being gaudy.

**Some subjects or key forms in the picture can naturally cross the boundary of the middle collage color block area**, breaking through the original area boundaries and extending into the white space, forming foreground and background layers, spatial pauses, and a more atmospheric visual relationship; this crossing should be restrained and designed, making the picture appear more agile rather than being neatly framed.

A small amount of text intervenes, with **casual, scribbled, soft handwritten English short phrases** dotted in the large areas of white space, like casual notes in personal diaries or independent publications. The text should be small and light, forming a natural rhythm with the subject and white space, without overshadowing the main theme.

Overall atmosphere should be **quiet, retro, healing, minimalist, and artistic**, like an artistically reconstructed paper card. The paper surface can have a slight aging texture, with **faint fine grain noise like Risograph printing** superimposed to enhance the paper and printing texture. Overall avoid heavy shadows, realistic rendering, strong three-dimensionality, complex decorations, filling the screen, and templated effects.
