Portrait dans un Cube de Verre Flottant

Cinematic vertical full-body fashion portrait of [a stylish adult man] standing at the exact center of a gigantic transparent glass cube suspended high above a sea of clouds at golden hour. He faces the camera with a calm, confident expression, one hand resting in his coat pocket and the other relaxed at his side, featuring [realistic male facial features or matching the reference photo]. He wears an elegant monochrome cream ensemble: a long beige trench coat, an ivory turtleneck sweater, high-waisted white trousers, and polished light-colored dress shoes. The tall rectangular glass cube features green-tinted edges, visible corner seams, a reflective floor, and subtle refractions, floating over distant snow-capped mountains on the horizon. Floating inside and outside the cube are 60 white feathers of varying sizes and 18 broken crystal fragments catching the sunlight. Warm golden backlighting, crisp golden rim light on the coat, clear blue upper sky, soft cloud depth, and three distinct starburst flares: one strong flare on the right horizon, one subtle flare near the left mountain peak, and one interior reflection flare near the bottom right. Centered symmetrical composition, dramatic high-fashion editorial styling, ethereal and surreal atmosphere, no text, no watermarks.
