  "prompt": "A square, 1024x1024 image in a painterly, slightly impressionistic style evoking a sense of mystery and melancholy. The central image is a solitary, gnarled olive tree with deep, dark roots visible, partially submerged in swirling, deep indigo and smoky grey water. The water's surface reflects faint, distorted, warm golden light, suggesting a distant, obscured sun or memory. The tree's branches are reaching upwards, some bare and stark, others with a few hesitant, vibrant green leaves. The overall color palette is a rich contrast of deep blues, charcoals, and earth tones, with pops of muted gold and a hint of dark, mossy green. The atmosphere is contemplative and evocative, with a soft, diffused light that hints at hidden depths. Compositionally, the olive tree is off-center, creating a dynamic yet balanced visual, with the water filling the lower portion and the branches reaching into the upper negative space. Professional audiobook cover aesthetic, square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name.",
