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 woman, strictly preserving her authentic facial identity, warm smile, and exact wavy light-brown hair. She is in the identical pose in the same sun-dappled park, holding the same smartphone in her raised hand to take a selfie. She is holding the identical Yorkshire Terrier in her other arm. The key difference is the color of her button-down shirt: it is now a soft, medium **grey** linen, while retaining the same texture, cut, and fit as the white one in the reference. The background remains the lush, soft-focus park foliage. The lighting is natural and soft. The focus is sharp on both the woman and the dog, highlighting their bond.
