  "prompt": "A professional audiobook cover art illustration, square format 1024x1024 pixels. The style should be dark, gritty, and cinematic, evoking a sense of urban mystery and suspense. The central imagery features a lone, imposing silhouette of a man with broad shoulders, standing resolutely on a rain-slicked city street at night. His back is partially turned, suggesting his watchful presence and readiness for action. Around him, the city lights create a blurred, atmospheric backdrop of neon signs and distant headlights, casting long, distorted reflections on the wet asphalt. The color palette is dominated by deep blues, shadowy grays, and sharp, contrasting highlights of cold, electric light (like blues and whites from streetlights and neon). There's a subtle sense of danger and isolation, but also resilience in the figure's stance. The overall mood is tense, moody, and intriguing, suitable for a crime thriller. Focus on atmospheric lighting and composition to create depth and drama. No text, no letters, no words, no title, no author name.",
