"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 close-up portrait photograph, strictly in a 1:1 square aspect ratio, capturing the woman from the reference image in the identical pose. She gazes downward with a gentle, introspective expression outdoors during a snowfall. Delicate snowflakes rest softly on her long dark hair and dark clothing. The background is a soft, blurred winter snowscape. Natural overcast winter lighting, shallow depth of field, sharp focus on her face.
