Ultra-realistic fine-art studio portrait of an adult woman in a dramatic “spider pose”, inspired by contemporary dance and sculptural fine-art photography. Preserve the facial characteristics of the reference image as faithfully as possible, with jet-black, thick, glossy hair styled naturally. She is positioned lying to the floor in a sexy pose, to create a striking silhouette, and her legs arranged in an elegant asymmetrical composition. Soft directional chiaroscuro lighting emphasizes the geometry of the pose, natural anatomy, elegant contours, and the interplay of light and shadow. Minimalist warm-gray studio background, fine-art photography aesthetic, museum-quality composition, realistic skin texture, natural proportions, cinematic shadows, 85mm lens, subtle depth of field, sophisticated contemporary art photography. Focus on movement, symmetry, anatomy, silhouette, and artistic composition, with a refined non-sexual fine-art atmosphere.
