  "prompt": "A square 1024x1024 digital painting, in the style of Belle Époque art nouveau and romanticism. The image depicts a solitary, ethereal woman with flowing, dark hair, her face turned away, gazing out of a rain-streaked window. Soft, diffused light emanates from an unseen source, casting subtle shadows and highlighting the delicate features of her profile and the textures of her vintage clothing, perhaps a velvet or silk dress in deep jewel tones like emerald green or sapphire blue. Outside the window, a blurry, impressionistic view of a Parisian street at dusk, with gas lamps casting a warm, hazy glow and distant silhouettes of horse-drawn carriages. The mood is melancholic, intimate, and dreamlike, with a soft focus on the background elements. The color palette is dominated by muted, rich tones: deep blues, purples, moss greens, and warm sepia, with subtle hints of gold in the light. The composition is centered on the woman, with the window frame creating a subtle division, evoking a sense of longing and introspection. The overall aesthetic is sophisticated, emotional, and evocative of a bygone era, suitable for a timeless literary work.",
