(photorealistic:1.4), RAW photo, masterpiece, best quality, ultra-detailed. A stunning young woman in her early 20s with long, vibrant red hair and captivating bright blue eyes is taking a mirror selfie in her bedroom. She has a slender yet athletic build with a very toned stomach and defined abs. She looks directly and confidently into the camera. With her right hand, she is lifting her tight, light-blue t-shirt all the way up, completely exposing her massive, perfectly round, and perky bare breasts. Her tits are heavy and full, with pale, smooth skin. Her nipples are a delicate pink color, fully erect and pointing forward. The background is a simple room with beige walls, a carpeted floor, and a white door. The lighting is soft and natural, highlighting the contours of her body and the full shape of her naked breasts.
