Cluttered or dark backgrounds that distract from the light, simplistic setting; any additional figures or objects that may shift focus away from Monroe; overly harsh or dramatic lighting that creates unflattering shadows or highlights on her face; exaggerated facial expressions that don't align with Monroe's characteristic allure; hair that appears stiff or unnaturally positioned instead of fluidly floating; and any modern styling or makeup that conflicts with Monroe's iconic 1950s look. Ensure the photograph features only Marilyn Monroe, capturing her essence without additional subjects.
