  "prompt": "A minimalist, highly atmospheric square 1024x1024 image for an audiobook cover. The style should be reminiscent of bleak, existentialist art with a touch of surrealism. The central focus is a single, weathered, gnarled tree branch extending diagonally from the bottom left corner towards the upper right. From one of the smaller twigs of this branch, a single, delicate, translucent white feather is gently falling. The background is a vast, textured expanse of deep, muted indigo and charcoal gray, with subtle hints of a distant, barely visible, pale moon or a faint, diffused light source. The mood is melancholic, introspective, and tinged with a profound sense of solitude and fragility. The overall composition should evoke a feeling of vast emptiness and a singular, poignant detail. No text, no letters, no words, no title, no author name. High-resolution, professional audiobook cover aesthetic.",
