  "prompt": "A square 1024x1024 professional audiobook cover design. The image evokes introspection and philosophical depth. Central to the composition is a solitary, ethereal black horse, rendered in a slightly impressionistic, almost sketched style, standing calmly on a misty, undefined plain. The horse's form is clear but its edges are soft, suggesting it's a symbol rather than a literal creature. Behind it, the background is a gradient transitioning from a deep, muted indigo at the bottom to a soft, ethereal lavender or pale grey at the top, creating a sense of vastness and quiet contemplation. Subtle, diffused light sources emanate softly, casting a gentle, moody glow. The overall mood is one of quiet contemplation, existential questioning, and profound inner reflection. The color palette is sophisticated and muted, featuring deep indigos, soft lavenders, subtle greys, and hints of pale, misty light. No text, no letters, no words, no title, no author name, just the artwork.",
