Cinematic Eclipse Disintegration Portrait

Create an ultra-realistic cinematic 8K full-body portrait of {argument name="character name" default="a brooding young man"} standing in side profile on a vast cracked wet asphalt plain under a dark stormy sky. The subject has {argument name="hair and beard" default="messy black hair and a short dark beard"}, a serious downward gaze, and a slim athletic build. Dress him entirely in distressed black clothing: one oversized worn black T-shirt, one long tattered sleeveless black outer layer or open vest trailing in the wind, one pair of black cargo pants, and one pair of heavy black lace-up combat boots. Behind him place one enormous circular eclipse-like portal: a nearly black disk outlined by a blazing molten golden ring, with sparks, embers, and fiery cracks along the circumference. Make the left half of the man’s body disintegrate into ash, smoke, dust, and glowing orange particles, as if being pulled into or burned away by the portal; the right half remains solid and sharply detailed. Use high-contrast dramatic lighting, warm golden rim light from the portal, cool gray ambient storm light, volumetric smoke, flying embers, realistic fabric texture, wet reflective ground, and a desaturated charcoal-and-gold color palette. Composition should be vertical, full body centered slightly right, portal filling most of the background, low horizon, cinematic depth, no text, no watermark, no extra people.
