  "prompt": "A dark, atmospheric, abstract composition suitable for a psychological thriller audiobook cover. The central element is a stylized, fragmented human silhouette, perhaps formed from swirling shadows or abstract geometric shapes, hinting at a fractured psyche. Within or around the silhouette, subtle, ethereal elements suggest whispering or silence – wisps of smoke, faint outlines of moth wings, or delicate, broken geometric lines. The color palette is predominantly deep indigo, charcoal grey, and hints of muted, blood-red or sickly green, creating a sense of unease and mystery. The lighting is dramatic and chiaroscuro, with deep shadows and stark, isolated highlights. The overall mood is one of claustrophobia, intellectual dread, and an unsettling beauty. The composition should be balanced and striking, with a sense of depth and an implied narrative, presented as a professional, square (1024x1024) graphic without any text.",
