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, high-detail portrait photograph, adapted to a 1:1 square aspect ratio, featuring the woman in the same foggy, atmospheric field by the wooden fence. Crucially, her specific facial identity, authentic eye shape, eye color, and distinct natural, long curly hair (including the specific texture, volume, and highlights) are fully and seamlessly integrated, strictly preserving her unique features while perfectly matching the original pose. She is wearing the identical dark green turtleneck sweater and black maxi skirt, holding the sheer black fabric which billows in the wind. The background of the wet grass, weathered fence, misty pine forest, and grey sky is retained and composed to fit the square frame. The soft, diffused light highlights her features. Every detail of her face and hair must match the reference image perfectly.
