“A dark, cinematic book cover featuring a mysterious man wearing a sinister clown mask inspired by a joker aesthetic (not copyrighted), with smeared face paint, a twisted grin, and haunting eyes visible through the mask. He stands in a dimly lit urban alley at night, with neon lights faintly glowing behind him. The atmosphere is gritty and tense, with subtle fog and rain reflecting light on the ground. The man wears a dark trench coat, slightly open, giving a sense of danger and unpredictability. High contrast lighting, dramatic shadows, realistic style. Leave space at the top for the book title and at the bottom for the author name. Color palette: deep purples, blacks, reds, and neon highlights. Ultra-detailed, 4K, professional thriller/horror novel cover design.” Ver más
