"A realistic, sinister clown, inspired by Pennywise, crouches within a dimly lit arched doorway. The clown's face is malevolent, with exaggerated features and a disturbing smile. The clothing is detailed and colorful, with vibrant ruffles and stripes. The archway is rendered realistically, with shadows and textures suggesting a damp, confined space. The background is a dark, realistic setting with a suggestion of overgrown grass. The overall style is realistic and unsettling, capturing the horror of the scene."
