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-quality digital art portrait in a 1:1 square aspect ratio, maintaining the exact multi-panel composition and glowing neon-blue light-frame effect. The central large portrait of the man smiling and wearing sunglasses is preserved, but his entire facial identity, eye shape, eye color, facial hair, and hair texture are completely and seamlessly replaced by those of the user's reference image. The three surrounding profile panels (top-left, top-right, middle-left) are also updated to show the user's specific facial identity and hair texture from different angles. The man retains the black jacket and the dark, textured background with electric blue light trails. The reflections of a city street scene in his sunglasses are kept. Aspect ratio 1:1.
