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 precisely detailed, photorealistic square-format (1:1 aspect ratio) photograph of the woman, seated in the same sunny cafe environment. Crucially, her specific facial identity, exact eye shape (including the gentle squint), authentic blue-green eye color, and distinct natural hair characteristics (messy bun with specific loose, curled tendrils) are fully and seamlessly integrated, strictly preserving her authentic look. She maintains the identical pose, resting her chin on her hand with a warm, winking expression. She wears the identical white ribbed cardigan, pearl earrings, and necklace. The "Café Kitsuné" cup, the open book, the wall collage with the "you are beautiful" note, and the "PRADA" and "OGAWA KAZUMASA" posters are all retained and clearly visible within the square frame. The warm, golden sunlight illuminates the scene, highlighting her features. Every detail of her face and hair must match the reference image perfectly while adapting to the new aspect ratio and framing.
