Ensure that the generated image does not include unrealistic or grotesque distortions that may compromise the overall quality. Avoid excessive exaggeration of facial features, body proportions, or clothing elements that could make the character appear comical or implausible. Additionally, steer clear of overly bright or saturated colors that might detract from the eerie atmosphere. Maintain a balance in lighting, avoiding extreme contrasts that could obscure essential details or lead to visual inconsistencies. Lastly, prevent the inclusion of elements that may inadvertently resemble unrelated themes, ensuring a cohesive and genuinely frightening portrayal of the 1970s killer janitor.
