  "prompt": "A moody, atmospheric digital painting for an audiobook cover. The scene depicts a vast, slightly misty river landscape at twilight. In the foreground, a single, gnarled, ancient tree stands silhouetted against the fading light, its branches reaching out like skeletal fingers. The river itself is a deep, reflective surface, mirroring the muted colors of the sky and the surrounding, indistinct shoreline. The color palette is dominated by deep blues, dusky purples, muted greys, and a hint of pale, fading orange or pink on the horizon. The overall mood is one of quiet contemplation, nostalgia, and a touch of mystery. The style should be painterly and evocative, with a focus on texture and light. The composition is centered on the tree and the river, with a sense of depth leading into the distance. Professional audiobook cover aesthetic, square 1024x1024 format. NO text, NO letters, NO words, NO title, NO author name.",
