  "prompt": "A painterly, atmospheric illustration for an audiobook cover, in the style of 19th-century Russian realism with a touch of romanticism. The scene depicts a grand, slightly decaying aristocratic estate at twilight. A lone, gnarled oak tree stands in the foreground, its branches reaching towards a pale, fading sky painted in hues of deep indigo, lavender, and soft ochre. In the distance, partially obscured by a gentle mist rolling across an expansive, manicured lawn, the silhouette of a large, classical manor house with dimly lit windows can be seen. The mood is one of melancholic beauty, quiet reflection, and a sense of faded grandeur. The overall composition should evoke a feeling of lingering memories and subtle emotional depth. The image should be rendered with soft brushstrokes and a muted, elegant color palette. Square 1024x1024 format, professional audiobook cover aesthetic. NO text, NO letters, NO words, NO title, NO author name.",
