Радостный Гелий

Replace the entire head of the person in the original image with the head from the second reference image. Cut and transfer the complete head (face, hair, ears, and skin) from the reference image and place it naturally onto the original body. Do not generate a new face. Do not keep any part of the original head. Remove the original face, hair, beard, and mustache completely. Keep the original body, clothes, pose, background, lighting, and camera angle exactly unchanged. Make the head replacement seamless and realistic.
