  "prompt": "A dark, atmospheric, and emotionally charged visual artwork suitable for a gothic mystery audiobook cover. The scene depicts a weathered, ancient mansion shrouded in mist and twilight, with a single, dimly lit window casting a faint, eerie glow. In the foreground, a wilting, thorny rosebush with dark crimson petals is intertwined with a decaying wooden fence, symbolizing hidden secrets and a broken past. The color palette should be dominated by deep indigos, muted grays, shadowy purples, and hints of blood-red in the rose petals. The mood is melancholic, foreboding, and introspective. The composition should be dramatic, with a slightly low angle looking up towards the imposing house, creating a sense of vulnerability and mystery. The style should be painterly with a touch of photorealism, evoking a classic book cover aesthetic. Aspect ratio 1024x1024. No text whatsoever.",
