Highly detailed photorealistic full-body portrait of a beautiful adult woman in her mid-20s standing in an open wooden doorway, viewed from a rear three-quarter angle looking through the door frame. She has long straight dark-blonde hair falling down her back, with a small gold hair clip 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, firm perky medium-to-full breasts, and a plump, firm, round, high and shapely ass with smooth soft curves and realistic skin folds under the cheeks. She is completely nude except for a large soft white bath towel that she holds against her front and lower body with one hand, the towel draping down from her hips and covering her front while leaving her entire bare back, waist, and plump round buttocks fully exposed. Her body is turned mostly away from the camera as she looks back over her left shoulder with a soft, slightly surprised expression, barefoot on wooden flooring. Soft natural indoor lighting casting gentle shadows across her skin and the textured white towel, sharp focus on skin texture, the firm curves of her ass, the fabric folds of the towel, individual hair strands, the wooden door frame and orange wall in the background. Ultra-detailed anatomy, realistic proportions, high-resolution skin details, cinematic composition, 8k, photorealistic, masterpiece quality.
