Create an original dystopian dark-surrealist image in a vast circular chamber beneath a dead city. At the center, an androgynous figure in a simple bone-white garment holds a small radiant sphere close to their chest, like the last living sun. Their ribcage is not exposed or injured; instead, an elegant external cage of thin black metallic branches grows around their torso and slowly closes around the light. Behind the person, thousands of suspended empty cages disappear upward into darkness. The person’s calm posture contrasts with the feeling that they are imprisoning their own light. Vertical 9:16 framing, full-body subject in the lower-middle of the composition, enormous negative space above, concentric brutalist architecture, cinematic scale, subtle fog. The small sphere provides warm ivory illumination on the figure; everything beyond it falls into cold charcoal and silver shadow. A single hairline of dark crimson circles the floor like a warning. Photorealistic materials, restrained surrealism, editorial sci-fi still, crisp silhouette and intense emotional clarity. Color palette: deep charcoal, obsidian, bone white, cold silver, faint ivory light, minimal dark crimson. Constraints: original visual metaphor; no exposed anatomy, no injury, no recognizable person, no text, logos, signatures, borders, or watermark. Avoid: portrait close-up, split identity face, black goo, red eyes, gore, conventional angel or demon imagery, flames, decorative fantasy styling, imitation of any named artist.
