"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, 1:1 aspect ratio photograph of the man in the identical pose, holding the same puppy and taking a selfie. His exact facial features, eye shape, and hair are flawlessly integrated. The key difference is his t-shirt, which is now a deep charcoal black, replacing the original grey. All other elements, including the puppy's appearance, the phone, and the softly blurred park background, remain consistent."
