A photorealistic 8K image of a 20-year-old amateur Caucasian sweet feminine girl with a highly detailed realistic face, sharp angular features, and high cheekbones. She has very long, slightly hair, a fit feminine body with slim waist and sexy curved hip, large perky D-cup breasts with natural hang and stretch, a very slim toned waist, slender figure, subtle toned abs, flat stomach, and natural feminine softness. She's standing on the deck of a yacht in full sunny weather with bright natural lighting and soft shadows, fully topless, wearing a mono-color low-cut G-string thong. She has a sweet smile, hot sexy direct eye contact, in a full-body photo from above the knees, frontal view. Keep the background very minimal, maybe sea.
