  "prompt": "A square, 1024x1024, professional audiobook cover art. The image depicts a dimly lit, elegant hotel lobby from the 1930s. A grand, ornate staircase curves upwards, its dark mahogany wood reflecting the soft glow of art deco chandeliers. Plush velvet banquettes are arranged in intimate seating areas. A single, solitary silhouette of a man in a formal suit and hat stands at the bottom of the stairs, looking up. The atmosphere is one of sophisticated mystery, timelessness, and a hint of melancholy. The color palette is rich and deep, dominated by warm golds, deep burgundies, muted emerald greens, and shadowed browns, with subtle hints of moonlight filtering through tall, arched windows. The composition should evoke a sense of quiet contemplation and understated grandeur, inviting the viewer into a world of secrets. The overall mood is elegant, refined, and subtly dramatic.",
