  "prompt": "A square, 1024x1024 professional audiobook cover image. The visual style should be dark, moody, and evocative, leaning towards a gritty, rural realism with a touch of the macabre. The main imagery focuses on a solitary, gnarled, ancient oak tree silhouetted against a stormy, bruised twilight sky. Its branches are twisted and reaching like skeletal fingers. At the base of the tree, partially obscured by tangled roots and long, dry grass, lies a single, weathered wooden scythe, its blade dull and pitted, glinting faintly. The ground is dark, loamy earth, with fallen leaves and small, dark stones scattered around. Subtle, diffused mist or fog should be present, adding to the atmosphere of decay and foreboding. The color palette is dominated by deep, desaturated blues, greys, and earthy browns, with muted hints of a sickly, pale yellow or ochre in the sky. The overall mood is somber, melancholic, and laced with an undercurrent of dread and natural power. The composition should be balanced, with the tree as the central focal point, drawing the viewer into the desolate scene. The lighting is dim and dramatic, emphasizing shadows and textures.",
