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.This is a 1:1 aspect ratio full-body photograph of the same young person with blue hair, captured in a dynamic running pose. They are wearing the identical oversized light blue sweatshirt, beige wide-leg pants, and red-checkered slip-on sneakers, holding the swirly rainbow lollipop. The unique hand-drawn doodle elements—the stick figure on the left pulling the sweatshirt, the sweat droplets, the hash marks, and the motion lines—are preserved perfectly. The key instruction is that the individual's face, including the exact eye shape, eye color, and all natural hair characteristics (texture, volume, style, color, and hairline at the forehead) are fully and seamlessly replaced with the authentic likeness derived from the user's reference image, ensuring a perfect match to that identity while strictly maintaining the original pose, happy expression, clothing, and the detailed illustrative background.
