"Create an image of a man with a friendly demeanor, short grey hair, a neatly trimmed grey mustache, and a beard. He should be wearing a dark-colored plaid shirt. The image should capture the essence and style of 'The Simpsons' characters: over-exaggerated features, bright yellow skin, with a touch of realism to resemble the person in the uploaded photo. The background should be minimalistic to keep the focus on the character."
