  "prompt": "A dark, atmospheric digital painting suitable for a mystery or gothic novel audiobook cover. The scene depicts a cobblestone street in a European city at twilight. Old, ornate buildings with Gothic architectural elements line the street, their windows dark or emitting faint, flickering light. A thick, swirling mist hangs low, obscuring the ground and softening the edges of the buildings, creating a sense of mystery and depth. In the center of the street, a single, antique gas lamp casts a dim, warm glow, its light struggling to penetrate the fog. The overall mood is melancholic and intriguing, hinting at secrets hidden within the shadows. The color palette is dominated by deep blues, greys, and muted browns, with subtle hints of sepia and gold from the lamplight. The composition should be visually striking and immersive, conveying a sense of a forgotten, haunting place. Square 1024x1024 format, professional audiobook cover aesthetic, no text, no logos.",
