  "prompt": "A square, 1024x1024, professional audiobook cover art, no text. The image should depict a vast, ancient river flowing through a dramatic, slightly mist-shrouded landscape. Majestic, gnarled trees with exposed roots cling to the muddy banks.

The visual style should be a blend of realistic textures and painterly atmospherics, with a focus on depth and natural light.",
