  "prompt": "A square, 1024x1024 professional audiobook cover artwork. The style should be reminiscent of classic European literary art, with a slightly painterly yet realistic feel. The main imagery depicts a solitary, weathered oak tree standing on a rolling, autumnal landscape under a vast, diffused sky. Its branches, gnarled and reaching, symbolize generations and the passage of time. Scattered fallen leaves in warm hues of ochre, burnt sienna, and deep russet lie at its base, suggesting memory and heritage. The overall color palette is muted and rich, dominated by earthy tones, soft grays, and a gentle, diffused golden light that casts long, subtle shadows, evoking a mood of introspection, nostalgia, and enduring strength. The composition is balanced, with the tree as the central focal point, drawing the viewer into the scene and its implied narrative. The atmosphere is serene, contemplative, and slightly melancholic, hinting at the depth and complexity of human experience. No text, no letters, no words, no title, no author name.",
