  "prompt": "A moody, atmospheric digital painting suitable for a crime thriller audiobook cover. The scene depicts a solitary figure walking away from the viewer down a dimly lit, narrow cobblestone alleyway at night. Rain slickens the stones, reflecting the faint glow of a distant, flickering gas lamp. Shadows are deep and elongated, creating a sense of mystery and danger. A hint of dark, weathered brickwork is visible on the buildings flanking the alley. The overall color palette is dominated by deep blues, grays, and muted, burnt oranges from the distant light, with a hint of deep red staining a shadowy corner. The mood is somber, intense, and suspenseful. Square 1024x1024 format, professional book cover aesthetic. NO text, NO letters, NO words, NO title, NO author name.",
