  "prompt": "A minimalist, atmospheric, square 1024x1024 digital painting for an audiobook cover. The central imagery is a stylized, abstract representation of a human profile composed of swirling, ethereal ink or smoke, predominantly in deep, midnight blues and subtle, glowing amber tones. Within the profile, faint, almost subliminal outlines of classical architectural elements or celestial bodies can be perceived. The background is a gradient of soft, muted grays transitioning to a deep, velvety black at the edges, creating a sense of depth and mystery. The overall mood is contemplative, intellectual, and slightly melancholic, evoking the feeling of whispered words and profound thought. The lighting is soft and diffused, casting subtle shadows and highlights on the ink-like forms, giving them a three-dimensional, yet intangible quality. The style should be evocative of classic literature and intellectualism, aiming for a sophisticated and artistic presentation. No text, no logos, only the visual artwork.",
