Photorealistic portrait of a beautiful young woman in her early 20s with fair smooth skin, shoulder-length straight auburn hair with full straight bangs framing her face, large expressive brown eyes with long lashes, subtle eyeliner, full glossy lips, bright genuine smile showing white teeth, looking directly at the camera. She is completely nude, lying prone on a thick vibrant magenta-purple shaggy rug. Her upper body is propped up on her forearms with elbows on the rug, hands stacked under her chin, shoulders relaxed. Her back is strongly arched, pushing her large round buttocks high up in the air in a prominent heart-shaped view, while her lower body rests on the rug. She has large natural heavy breasts visible and hanging slightly beneath her chest due to the pose, slim waist, curvy hips. Soft natural indoor lighting, sharp focus on her face and body, realistic skin texture with subtle sheen, detailed hair strands, photorealistic, 8k, highly detailed, cinematic composition matching the exact framing where her smiling face is central in the foreground, raised buttocks prominent in the upper mid-section of the frame, gray armchair and room interior softly visible in the background.
