Eye shape, eye color, and exact natural hair characteristics are fully and seamlessly replaced by the user's uploaded reference image, strictly preserving the user's authentic facial identity, hair texture, and look perfectly while adapting to the pose. A high-resolution, professional full-body photograph of the woman, strictly preserving her authentic facial identity, expression, and exact hair characteristics, adapted to a 1:1 aspect ratio. The woman is in the identical walking pose on the same city sidewalk, with the same background buildings and cars in the soft-focus distance. She wears the same beige blazer, white t-shirt, blue jeans, and white sneakers. The brown leather tote bag is held in the same hand, and her left hand is in her pocket. The lighting is natural daylight. Every detail of her face and hair is rendered precisely.
