Realistic Casual Photo Identity Swap

Image composition task: Use the reference photo as the base visual guide. Reproduce the scene, pose, camera angle, framing, lighting, outfit style, and background environment. Depict the [designated subject] as the person in the frame. Maintain the same body orientation, hand position, head angle, and overall composition. Preserve the [candid mobile photo aesthetic], including subtle motion blur, natural room lighting, authentic skin texture, and realistic shadows. Avoid an artificial studio render aesthetic.
