Surreal figure in black turtleneck with iridescent sphere head

A full-body editorial photograph of a person wearing a sharp black turtleneck, standing against a clean off-white background. The person's head is replaced by a perfect iridescent sphere — glossy, holographic surface with cyan, deep purple, magenta and electric blue tones, with a bright specular highlight. The sphere looks like a premium 3D render floating naturally on the shoulders. Soft studio lighting, fashion editorial style, minimalist composition, shot from slightly below eye level. High resolution, photorealistic.
