  "prompt": "A square, 1024x1024 image for an audiobook cover. The style should be evocative and slightly melancholic, hinting at mystery and historical fiction. The central image is a weathered, old wooden door of an orphanage, slightly ajar, revealing a sliver of a dimly lit, empty hallway within. Sunlight streams through a high, grimy window to the left, casting long, dramatic shadows across the worn floorboards and the partial view of the hallway. The door itself is peeling paint, with a tarnished brass knocker. The color palette is muted, dominated by desaturated blues, greys, browns, and a touch of sepia for the aged feel. The overall mood is one of quiet mystery, forgotten childhoods, and lingering secrets. The composition is balanced, drawing the viewer's eye towards the enticing darkness of the interior. The aesthetic is professional and artful, suitable for a literary fiction cover. NO text, NO letters, NO words, NO title, NO author name.",
