  "prompt": "A moody, atmospheric digital painting suitable for a mature literary fiction audiobook cover. The central focus is a single, antique playing card, the Ace of Spades, partially obscured by swirling, ethereal smoke. The smoke has a deep, rich indigo and charcoal gray palette, with subtle hints of deep crimson and muted gold threads woven within. The background is very dark and blurred, suggesting a dimly lit, intimate, perhaps slightly disreputable, setting like a smoky backroom or an old study. The lighting is dramatic and chiaroscuro, casting deep shadows and highlighting the texture of the card. The overall mood should be one of mystery, contemplation, and a touch of foreboding, with a sophisticated, timeless feel. The image should be presented in a square 1024x1024 format, with a professional, high-resolution aesthetic, conveying depth and artistic intent without any text elements.",
