  "prompt": "A square, 1024x1024 professional audiobook cover illustration. The image depicts a mystical, slightly melancholic mountain landscape at dusk. In the foreground, a solitary, ancient, gnarled oak tree stands against a backdrop of jagged, mist-shrouded peaks. Faint, ethereal wisps of light, suggestive of folklore or ancient spirits, drift around the tree and in the valleys. The sky is a deep gradient of twilight blues and purples, transitioning to a pale, hazy orange near the horizon, where the last sliver of sun is visible. Subtle hints of dark green and brown dominate the palette, evoking a sense of mystery, age, and the wildness of nature. The overall mood is one of quiet contemplation, ancient power, and a touch of the supernatural. The composition is balanced, with the tree as a strong focal point, drawing the viewer into the depths of the landscape. The lighting is dramatic and atmospheric, with soft shadows and highlights that emphasize texture and form. No text, no logos, only artwork.",
