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 photorealistic, black and white portrait photograph, adapted to a 1:1 square aspect ratio, featuring the woman seated at the same outdoor café table. Her authentic facial identity, exact eye shape, eye color, and distinct natural hair characteristics (texture, length, and style) are fully and seamlessly integrated, strictly preserving her unique features while perfectly matching the original pose. She maintains a gentle smile and holds the coffee cup in her left hand, gazing at the camera. The dark, belted jacket and detailed nails are identical. The composition focuses tightly on her, with the chrysanthemums on the table and the detailed background foliage visible but adapted to the square frame, maintaining the soft, natural light and depth of field. Every detail of her face and hair precisely mirrors the reference image.
