  "prompt": "A professional audiobook cover art, square 1024x1024 format, in the style of moody romanticism and gothic art. The central image is a solitary, gnarled hawthorn tree silhouetted against a turbulent, stormy sky. Dark, brooding clouds are lit from within by flashes of distant lightning. The tree's branches reach out like skeletal fingers towards the stormy expanse. In the foreground, a windswept patch of heathland is visible, with sparse, tough grasses bending in the unseen gale. The overall color palette is dominated by deep indigos, charcoal grays, stormy blues, and muted, earthy browns. The mood is one of intense emotion, desolation, and untamed wildness. The composition is dramatic and evocative, with the tree as a focal point against the vast, overwhelming sky, conveying a sense of isolation and powerful natural forces. No text, no letters, no words, no title, no author name – purely visual artwork.",
