Hyper-realistic man in floating glass cube AI Image Prompt

Create a hyper-realistic cinematic vertical portrait of {argument name="character name" default="a stylish adult man"} standing full-body at the exact center of a gigantic transparent glass cube suspended high above a sea of clouds during golden hour. The man faces the camera with a calm, confident posture, one hand in his coat pocket and the other relaxed at his side; use {argument name="face identity" default="the provided facial identity exactly"} if a face reference is available, otherwise render a realistic male face. He wears an elegant monochrome cream outfit: a long beige trench coat, ivory turtleneck sweater, high-waisted white trousers, and polished light shoes. The cube is a tall rectangular transparent box with green-tinted glass edges, visible corner seams, reflective floor, and subtle refractions, floating in open sky with distant snow-capped mountains on the horizon below. Surround him with exactly 60 visible white feathers of varied sizes drifting inside and outside the cube, plus exactly 18 floating broken crystal or glass fragments catching the sunlight. Add 3 bright starburst light flares: one strong flare on the right side near the horizon, one smaller flare on the left near the mountains, and one bright reflection flare near the lower right inside the cube. The atmosphere should feel ethereal, luxurious, surreal, and heavenly, with soft warm backlighting, realistic cloud depth, blue sky, golden rim light on the coat, crisp reflections on glass, shallow cinematic haze, and ultra-detailed 8K photorealism. Use a vertical {argument name="aspect ratio" default="9:16"} composition, centered symmetry, full-body framing, dramatic fashion editorial styling, no text, no watermark, no logos.
