Edit the uploaded photo while preserving the person's identity, face, expression, head size, hairstyle, clothing, pose, shoulders, background, lighting, framing, and all other details exactly. Shorten the visible neck to about two-thirds of its original length (1.5 times shorter), using a subtle, anatomically natural adjustment between the jaw and shoulders. Keep the head and shoulders in their original positions as much as possible; avoid distorting the face, jaw, collar, clothing, or body. Maintain the original image quality, sharpness, resolution, natural skin texture, and photorealistic appearance. Do not add, remove, or alter anything else.
