4-grid candid portrait collage with one consistent face

Use the exact same face from the reference image and generate a 4-grid casual portrait collage - the energy of real candid moments captured in a single room, film grain aesthetic, completely unforced and human. Same simple setting across all four frames - a warm neutral textured wall in the background, a grid of small polaroid photos pinned casually to the wall behind her, soft warm practical room lighting, the same black oversized crew neck t-shirt throughout. Everything consistent, everything real. Each grid a completely different expression and pose, all natural, none performed: Top left - big genuine open smile, full teeth, eyes completely alive and crinkled, head slightly forward, pure unfiltered joy radiating. The smile that happens when someone says something actually funny. Top right - one hand raised loosely near the chin or cheek, body at a subtle angle, expression soft and thoughtful, lips slightly parted, eyes holding a quiet calm intensity. Contemplative and effortlessly beautiful. Bottom left - pure side profile, face turned completely away from camera, just the profile of the nose lips and jaw visible, hair falling naturally, expression neutral and clean. The frame that works because of what it hides. Bottom right - both hands raised in a casual playful shrug, a scrunched nose smile, eyes half closed in laughter, the most unguarded and silly expression of the four, completely human and lovable. Film grain heavy and analog throughout all four frames - warm tones, slightly underexposed feel, the specific look of a 35mm point and shoot camera. Consistent lighting and color across all four. Polaroid grid on the wall visible and slightly out of focus in each frame. Natural hair loose and real in every shot. Color grading warm and vintage - muted tones, lifted shadows, the exact aesthetic of the reference. Square 1:1 overall grid format. Ultra photorealistic, 8K, four moments, one person, infinite personality.
