"2D illustration of an 18-year-old young man with slicked-back black hair and shaved sides. He is a demon. the red fire reflecting sharply on his facial features. He has a sly, confident smirk on his face and props his cheek with one hand in a relaxed, almost mocking pose. He wears early 20th-century clothing dark coat, vest, trousers. Behind him, a foggy background with silhouettes of 20th-century London, rooftops and fog-shrouded buildings. Dramatic lighting, intense atmosphere, high contrast, stylized line art, dark fantasy aesthetic."
