Bradhamel art style. Extreme macro close-up of a human iris with intricate, radiating radial patterns in deep blues and golds, surrounding a perfectly black pupil; the texture resembles fine, organic filaments and layered scales, with golden-orange highlights concentrated near the pupil’s edge, creating a dramatic contrast against the dark background; high-resolution photorealistic detail, sharp focus on the central circular aperture, ambient lighting that accentuates the iridescent depth and surface complexity, no other elements present, centered composition, isolated on pure black to emphasize the eye’s vivid structure.
