Fashion Portrait in Cloud Glass Cube

Full-body fashion editorial portrait of [a stylish adult man] standing calmly at the exact center of a gigantic transparent glass cube suspended high above an endless sea of clouds at golden hour. The subject faces forward with hands in trouser pockets, wearing a monochrome warm-ivory outfit: a soft knit turtleneck, tailored pleated trousers, minimalist white sneakers, and a long flowing overcoat billowing dramatically to the right. He has [dark brown] neatly styled short hair and a softly blurred, anonymized face with natural skin tones. Setting: An enormous, perfectly geometric crystal-clear cube with glowing glass edges, reflective floor, prismatic rainbow flares, and corner highlights. Drifting around the exterior are floating white feathers and irregular diamond-like glass fragments glinting in the light. Composition & Lighting: Centered subject framed by the glass cube edges, full body visible from shoes to head, camera angled slightly below eye level. Warm low sun near the horizon on the right creates volumetric haze, golden rim light on the figure, lens flares, and soft glass caustics against a gradient blue and amber sky. Style: Photorealistic luxury fashion campaign aesthetic, sharp garment textures, refined gold-and-cream palette. Constraints: no text, no watermarks, no extra people, cube must remain fully transparent with the subject fully enclosed.
