Edit **only** the hands of both the man and the woman.
Replace the existing hands with anatomically correct, highly realistic human hands. Correct only the hands, fingers, thumbs, fingernails, joints, knuckles, palms, wrists, and skin details. Ensure correct finger proportions, natural anatomy, realistic nail shape, accurate joint structure, and believable muscle and tendon definition.
The hands must remain perfectly realistic even when the image is viewed at high resolution or zoomed in. Preserve fine skin texture, pores, subtle wrinkles, natural creases, veins where appropriate, and realistic fingernails without any AI artifacts.
Keep the original hand pose, gesture, perspective, lighting, shadows, skin tone, and overall style exactly the same.
Do **not** modify faces, hair, body, clothing, accessories, background, composition, colors, camera angle, or any other part of the image. Only improve the hands to professional photographic quality with flawless anatomy and natural detail.
