  "prompt": "A square, 1024x1024, professional audiobook cover art with a melancholic and contemplative mood. The image should feature a single, vintage, dimly lit grand piano on a slightly dusty, ornate stage. Moonlight streams through a tall, arched window in the background, casting long shadows and illuminating motes of dust dancing in the air. A single, wilting white rose lies on the piano keys. The color palette should be dominated by deep blues, muted grays, and warm, soft sepia tones, creating an atmosphere of faded grandeur and poignant memory. The lighting should be dramatic and chiaroscuro, emphasizing the solitary nature of the piano and the quiet emptiness of the space. The overall aesthetic should be evocative of classical music, lost dreams, and introspective reflection. NO text, NO letters, NO words, NO title, NO author name.",
