no signs of AI generation, no artifacts, no unrealistic smoothness, no overexposure, no distorted features, no exaggerated proportions, no unnatural lighting, no overly sharp edges, no low-resolution details, no blurry textures, no excessive gloss, no cartoonish effects, no plastic skin, no asymmetrical hands, no misshapen eyes, no pixelation, no AI patterns, no unrealistically perfect skin, no floating elements, no stiff posture, no uncanny valley effect, no unnatural symmetry.
