  "prompt": "A professional audiobook cover illustration, square format (1024x1024). The image should evoke a dark, unsettling, and psychological thriller atmosphere. Centerpiece is a silhouette of a person seemingly walking or floating in a dimly lit, eerie forest at night. Their form is slightly indistinct, suggesting a dreamlike or spectral quality. Gnarled, skeletal tree branches reach out towards the figure, some appearing to be made of shadow or smoke. The forest floor is covered in mist or fog, obscuring the ground and creating a sense of depth and mystery. Subtle, eerie light sources are present, perhaps faint moonlight filtering through a dense canopy or faint, glowing eyes in the dark. The color palette should be dominated by deep blues, blacks, dark grays, and hints of muted, sickly greens or pale, ghostly whites. The overall mood is one of suspense, fear, and disorientation, with a hint of the supernatural. The composition should be dramatic and engaging, drawing the viewer into the mystery. High detail, cinematic lighting, professional illustration style. No text, no letters, no words, no title, no author name.",
