  "prompt": "A professional audiobook cover art, square 1024x1024. The image depicts a dimly lit, cobblestone alleyway in Paris at night. Soft, ethereal moonlight filters down, casting long, distorted shadows. In the center, a silhouette of a lone figure stands, their form indistinct, hinting at mystery and perhaps a spectral presence. The atmosphere is moody and slightly eerie, with a touch of melancholic beauty. The color palette is dominated by deep blues, purples, and muted grays, with subtle hints of warm golden light emanating from distant, unseen windows. The composition should feel intimate yet vast, drawing the viewer into the scene. The overall aesthetic should be sophisticated and evocative, suitable for a mystery or fantasy thriller genre. No text, no letters, no words, no title, no author name.",
