  "prompt": "A dark, atmospheric audiobook cover, square 1024x1024 format, in a moody, realistic, painterly style. The central imagery features a solitary, silhouetted figure standing on a cobblestone street at twilight. Rain-slicked stones reflect the faint glow of a distant, single flickering gas lamp. In the background, a dense, fog-shrouded Victorian-era cityscape looms, with indistinct, towering gothic architecture. Subtle, deep shadows dominate, with a palette of deep blues, charcoal grays, muted purples, and touches of aged sepia from the lamp. The overall mood is one of mystery, suspense, and a hint of foreboding, evoking the feeling of being watched or pursued. The composition should feel slightly off-kilter, with a strong sense of depth and an overwhelming feeling of isolation. No text, no logos, just the artwork.",
