  "prompt": "A dramatic, high-contrast digital painting for an audiobook cover. The scene depicts a sleek, powerful submarine surfacing stealthily from a dark, turbulent ocean under a stormy, twilight sky. Silhouettes of jagged, dark cliffs rise in the background, hinting at a remote, dangerous coastline. The submarine's metallic hull gleams with a subtle, eerie blue light reflecting off the choppy water. Wisps of mist and spray are kicked up by the turbulent waves, creating a sense of urgency and isolation. The overall color palette is dominated by deep blues, dark grays, and hints of ominous purple in the sky, with the submarine's light providing a focal point. The composition is dynamic, with the submarine positioned slightly off-center, leading the viewer's eye towards the implied horizon. The mood is suspenseful, adventurous, and foreboding. Professional audiobook cover aesthetic, square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name.",
