Photorealistic full-body portrait of an adult woman reclining in a wooden sauna…

Prompt:

Photorealistic full-body portrait of an adult woman reclining in a wooden sauna, shot from a three-quarter side angle: she sits on the lower bench on top of a white towel, leaning back with both arms extended behind her and palms on the bench, chest lifted, head tipped back and turned slightly to the left in profile, legs extended forward with a gentle bend at the knees. Use the provided pencil body blueprint sketch as the body-proportion and pose guide; match its silhouette exactly (bust/waist/hips ratio, hips noticeably wider than waist, waist clearly narrower than bust and hips, thicker/full upper thighs, limb lengths). Use the sketch only for proportions/pose; render photorealistic details normally. Outfit: matte black short-sleeve cropped T-shirt (tight fit) and black string-tie bikini bottoms with thin side ties resting on the hips; barefoot; bare legs (no tights). Emphasize a pronounced hourglass silhouette, hips wider than the waist, defined narrow waist, and full upper thighs while keeping realistic anatomy. Environment: warm cedar/wood plank walls and tiered sauna benches, soft warm overhead sauna lighting creating a gentle sheen on skin, natural skin texture, subtle shadows along the torso and thighs, shallow depth of field, 35mm lens look, high-resolution editorial photography, clean scene free of text/logos/watermarks, only one subject, no distortions or extra limbs. Maintain the rounded rear/hip silhouette in side profile (no flattening) and keep the pose exactly as guided; long deep dark-brown hair, deep dark-brown hair.
