  "prompt": "A square, professional audiobook cover artwork, 1024x1024 pixels. The image should evoke a sense of nostalgic, slightly melancholic, and warmly lit historical setting. The central focus is a weathered, old stone castle, subtly integrated into a rolling Scottish landscape. The castle's architecture should suggest age and perhaps a touch of faded grandeur, with ivy creeping up its walls. In the foreground, a winding, dusty path leads towards the castle. The atmosphere is one of early morning or late afternoon light, casting long shadows and bathing the scene in warm, golden-ochre and muted sepia tones. The sky is a soft, hazy blue with hints of pale orange or pink near the horizon. The overall mood is introspective and evocative, hinting at stories of lives lived and secrets held within the castle walls. The visual style should be painterly and atmospheric, with a rich texture and a slightly soft focus, reminiscent of classic oil paintings. No text, no letters, no words, no title, no author name.",
