Anonymized Fashion Collage Poster

Create a photorealistic gallery scene showing a large vertical fashion portrait collage poster hanging on a smooth beige museum wall, viewed straight-on with a polished concrete floor and soft overhead gallery lighting. The poster is a tall 2:3 rectangle with a vivid pastel rainbow gradient background blending coral pink, cyan, turquoise, yellow, lavender, and mint, overlaid with circular portrait cutouts. Center the main subject: a glamorous adult woman with [hair color], wearing an extravagant flowing couture dress in [dress colors]; the dress has huge sculptural billowing sleeves, a wrapped V-neck bodice, and a cinched pink waist, with fabric sweeping dramatically across the poster. Her face should be intentionally anonymized by a smooth vertical blurred rectangular mask. Surround her with exactly 8 smaller circular portraits: 3 circles along the top, 3 circles across the middle-lower row, and 2 circles along the bottom, each showing the same woman in different fashion poses; exactly 5 of the small portraits are black-and-white and exactly 3 are full-color. The small portraits include: top-left black-and-white bare-shoulder pose, top-center color close-up with dark hair, top-right black-and-white ruffled high-neck pose, middle-left black-and-white windblown hair pose, middle-center color hot-pink outfit with hands near chin, middle-right black-and-white draped garment pose with hand near face, bottom-left black-and-white seated hand-near-face pose, bottom-center color yellow outfit with hands near face, and bottom-right color emerald-green puff-sleeve outfit with hand on hip. Apply the same anonymizing rectangular blur over every visible face. Make the poster crisp and glossy with a subtle drop shadow on the wall. Keep the surrounding gallery minimal, neutral, and spacious; no typography, no logos, no captions, no extra people.
