  "prompt": "An atmospheric, painterly digital artwork depicting a quintessential Heidelberg scene bathed in the warm, golden light of late afternoon. The focus is on the iconic Old Bridge (Alte Brücke) with its stone arches, leading towards the silhouette of Heidelberg Castle perched majestically on the hill. Below the bridge, the Neckar River flows gently, reflecting the warm hues of the sky and the surrounding architecture. Cobblestone streets and half-timbered houses with charming details line the riverbank, suggesting a romantic, historical European town. The mood is nostalgic, serene, and imbued with a sense of timeless beauty. The color palette is dominated by warm golds, soft oranges, earthy browns, and muted greens, with deep blues in the shadows. The composition should be balanced and visually appealing, creating a sense of depth and inviting the viewer into the scene. Square 1024x1024 format, professional audiobook cover aesthetic, no text, no letters, no words, no title, no author name.",
