  "prompt": "A square 1024x1024 image depicting a dark, atmospheric scene within a post-apocalyptic subway tunnel. The central focus is a solitary, young male figure, Artyom, illuminated by the faint, flickering glow of a single torch held in his hand. His face is shadowed, showing a mix of determination and apprehension. The tunnel walls are rough, damp concrete, partially crumbling, with exposed rebar and pipes. In the background, deeper into the darkness, subtle, unsettling shapes can be discerned, hinting at unseen threats. Wisps of unnatural fog or steam curl around the edges of the torchlight. The overall color palette is dominated by deep blues, grays, and muted earthy tones, with the warm, orange-yellow glow of the torch providing a stark contrast and the only source of significant light. The composition is claustrophobic, emphasizing the confined and dangerous environment, with a slightly low-angle perspective to make the tunnel feel imposing. The mood is tense, mysterious, and survival-oriented. Professional audiobook cover aesthetic, no text.",
