Avoid duplicating heads or facial features. Do not include distorted or contorted appendages. Ensure that the hands are not poorly illustrated or disfigured. Omit any mutated or levitating limbs. Avoid sketchy or grainy details. The anatomy should be accurate and well-drawn, without any mutilation or disproportionate features. The facial features should be well-sketched and not blurry. Exclude any watermarks or signatures. The artwork should have high contrast and proper exposure, avoiding being overexposed or underexposed. Ensure the overall quality is not subpar, amateurish, or beginner level.
