Replace the slippers in the original image with the uploaded product image. Keep the model, pose, hands, background, lighting, camera angle, and composition exactly the same. Make the new product look naturally held by the model with correct scale, perspective, shadows, and realistic material details. Remove all original text, logos, letters, and watermarks completely, and repair the background naturally. The final image should look like a professional luxury e-commerce product advertisement with no editing artifacts or AI-generated appearance.
