Create a high-resolution 9:16 autumn fashion collage made from 12 separate photographs arranged in a clean 3-by-4 grid. Each photo should show a stylish young woman with a different random face and hairstyle, not resembling any real person or celebrity. Show cozy outdoor poses and scenes: sitting beside an old glass greenhouse holding a takeaway coffee cup; walking along a tree-lined path covered with orange fallen leaves; sitting alone on a wooden bench deep in the forest; leaning against a park fence; resting on stone steps with a leather handbag; sitting casually on a green park bench in a skirt and knee-high boots; sitting sideways on a bench; standing beside a calm lake surrounded by orange trees; and standing on a misty path framed by tall trees. Mix long wool coats, oversized sweaters, scarves, wide-brim hats, neutral trousers, knit dresses, and boots in earth tones such as beige, brown, cream, gray, and black. Use warm golden-hour lighting, soft cinematic color grading, shallow depth of field, and creamy bokeh so the full collage feels unified, polished, and like a high-end fashion magazine or influencer editorial. Do not include signatures, logos, watermarks, real brand marks, or unrelated text. Output a high-quality 9:16 image suitable for GPT Image 2.
