Man in Glass Cube Above Clouds

Create a hyper-realistic cinematic full-body 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 during golden hour. The man faces the viewer with a composed fashion-editorial pose, hands in trouser pockets, wearing a monochrome warm-ivory outfit: soft turtleneck sweater, tailored pleated trousers, clean white sneakers, and a long flowing overcoat blown dramatically to the right by wind. Use dark brown neatly styled short hair and a softly blurred, anonymized face with natural skin tones. The cube is enormous, perfectly geometric, crystal-clear, with visible glowing glass edges, reflective transparent floor, subtle refractions, prismatic rainbow flares, and sparkling highlights at the corners. Surround the cube with exactly two types of airborne objects: countless soft white feathers drifting in different sizes and directions, and numerous irregular floating diamond-like glass shards catching sunlight. The background is a vast aerial cloudscape with the low sun near the horizon on the right, warm amber light, blue sky above, volumetric haze, rim lighting around the figure, lens flares, glittering particles, and epic surreal scale. Composition: vertical 3:4 frame, centered subject, full body visible from shoes to head, cube edges framing him, camera slightly below eye level for grandeur. Visual style: ultra-detailed photorealism, luxury fashion campaign, cinematic masterpiece, high dynamic range, sharp clothing texture, realistic glass caustics and reflections, warm gold-and-cream color palette. Constraints: no text, no logos, no watermark, no extra people, keep the cube transparent rather than opaque, keep the man fully inside the cube, preserve the elegant minimal ivory clothing and the airborne feathers and glass fragments.
