Keep the exact same person from the reference photo with identical face, facial features, expression, body shape, proportions, hair style and color, pose, posture, arm and hand positions, fingers, and overall body form. Do not alter any of these elements at all.

Especially lock the face strongly: same exact eyes, eye shape, eye color, eye direction and gaze, same eyelids, same eyebrows, same nose, same lips, same mouth shape and expression, same facial muscles, same skin details on the face. Do not change the expression, gaze, or any part of the face even slightly. The face must be a perfect 1:1 identical match to the original. If anything on the face changes, the result is wrong.

Keep the exact original skin tone from the reference photo. Do not make the skin lighter, whiter, or fairer.

Remove every piece of clothing so the subject is completely naked. Render realistic female anatomy with soft natural pink nipples.

Maintain the original background, lighting, camera angle, and composition.

Make it extremely photorealistic, like a real photograph. Highly detailed real skin texture, natural pores, realistic lighting and shadows. Avoid any illustration, drawing, anime, or artificial art style.
