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 portrait photograph (1:1 aspect ratio) of the same woman and Golden Retriever in their identical crouching pose in the sunny park. The woman's authentic facial identity, warm smile, and exact wavy light-brown hair texture are perfectly preserved. The Golden Retriever, with its specific friendly expression and happy pant, is also identical. The key change is the color of the woman's denim jacket: it is now a rich, deep **red** denim, while retaining the exact same cut, texture, and fit as the blue one in the original image. Her blue jeans and white sneakers remain unchanged. The park background with soft-focus trees and grass under warm sunlight is preserved. The focus is sharp on both the woman and the dog, highlighting their bond.
