Keep image 1 completely unchanged in every detail, including the person’s body, pose, clothing, hairstyle, lighting, background, camera angle, framing, and proportions. Replace only the face of the person in image 1 with the face of the person from image 2, matching it as accurately as possible one-to-one. Preserve the original head position, facial angle, expression, skin tone integration, lighting, shadows, and perspective so the result looks fully natural and photorealistic, with no visible signs of editing.
