Highly detailed photorealistic full-body portrait of a beautiful adult woman in her mid-20s sitting on a large white modern sofa in a bright contemporary living room, viewed from a slightly elevated three-quarter frontal angle. She has long straight dark-blonde hair falling over her shoulders and down her back, with two small pink hair clips on the right side of her head. Flawless smooth pale light skin with realistic subtle pores, soft natural skin texture and gentle highlights. Slim elegant waist, toned flat stomach with soft abdominal definition, firm perky medium-to-full breasts, and a plump, firm, round, high and shapely ass with smooth soft curves partially visible as she sits. She is wearing a tight pink sports-bra style crop top that hugs her firm breasts and a matching pink thong that sits high on her hips, the thin fabric framing her round buttocks and toned thighs. Her body is relaxed and slightly reclined on the sofa, one arm resting along the backrest, legs bent and crossed at the knees with bare feet visible, knees drawn up in a natural seated pose. She looks directly at the camera with large bright blue eyes, soft natural makeup, a gentle subtle smile and a calm seductive expression. Soft natural daylight mixed with warm indoor light from a modern fireplace in the background, realistic volumetric lighting, sharp focus on skin texture, body contours, fabric details of the pink underwear set, individual hair strands and the soft cushions. Ultra-detailed anatomy, realistic proportions, high-resolution skin details, cinematic composition, 8k, photorealistic, masterpiece quality.
