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 square-framed, studio photo collage featuring a 2x2 grid of four distinct portrait shots of the young woman from the reference image against a solid blue background. She is wearing a white t-shirt with French text ("Bonne Journée") and a blue bow graphic, a silver wristwatch, and small earrings. Top-left panel: she cups her face with both hands with a surprised, wide-eyed expression. Top-right panel: she holds her index finger to her lips in a shushing gesture. Bottom-left panel: she rests her chin on her stacked hands with a thoughtful, pouty expression. Bottom-right panel: she looks directly forward with a calm, gentle expression while adjusting her hair. High-detail focus on preserving facial identity and authentic expressions across all panels. Aspect ratio 1:1.
