  "prompt": "A minimalist, darkly atmospheric audiobook cover. The central image is a single, antique, tarnished silver pocket watch, slightly ajar, with intricate gears visible within. The watch is casting a long, sharp, dramatic shadow across a textured, desaturated background that suggests aged paper or worn leather. The overall mood is one of suspense, mystery, and impending doom. The color palette is dominated by deep greys, muted metallic silvers, and subtle hints of dark, desaturated crimson within the shadow, giving a sense of dried blood or hidden danger. The lighting is stark and dramatic, with high contrast between light and shadow, creating a sense of unease. The composition is centered and tightly framed on the watch and its shadow, evoking a sense of being trapped or watched. The aesthetic should be sophisticated and professional, suitable for a psychological thriller audiobook. Square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name.",
