Colorful Fashion Collage Poster

Goal: Create a realistic gallery-view mockup of a vibrant fashion portrait collage poster featuring an anonymous female fashion model with all faces intentionally obscured by soft vertical rectangular blur masks. Canvas: Wide 16:9 image showing a tall vertical poster centered on a minimalist beige-gray gallery wall, concrete floor, subtle ceiling track details, soft museum lighting, and a faint decorative sparkle/star mark near the lower right of the room. The poster itself is portrait-oriented, slightly raised from the wall with a soft drop shadow. Poster layout: Use a bright pastel gradient background with overlapping circular color fields in cyan, pink, yellow, coral, mint, and lavender. Place exactly 9 visible model images on the poster: 1 large central full-color fashion portrait and 8 smaller circular portraits arranged around it. Subject details: The central model has long dark wavy hair and wears an extravagant high-fashion dress with oversized flowing sleeves and color-blocked fabric in turquoise, hot pink, lemon yellow, and emerald green. The fabric should look voluminous, silky, wind-swept, and sculptural, with dramatic folds and movement. Counted circular portraits: Include exactly 8 circular portrait cutouts: 1 top-left black-and-white shoulder portrait, 2 top-right black-and-white portrait in a draped top, 3 middle-left black-and-white hair-blown portrait, 4 middle-center full-color portrait in a bright pink outfit with hands near chin, 5 middle-right black-and-white portrait with one hand near face, 6 bottom-left black-and-white seated or leaning portrait with hand near face, 7 bottom-center full-color portrait in a yellow outfit, 8 bottom-right full-color portrait in a green outfit with oversized sleeves and one hand on hip. All circular portraits must have gray circular photo backgrounds and the same soft rectangular face-obscuring blur. Visual style: Editorial fashion magazine collage, polished photographic realism, saturated candy colors, clean poster design, premium gallery installation mockup, balanced composition, sharp details on clothing and hair, no typography, no logos, no watermark.
