Woman on balcony above dreamy fantasy city at twilight

A solitary woman stands on a balcony overlooking a sprawling, whimsical cityscape at twilight. The architecture is a fantastical blend of Art Nouveau curves and celestial motifs, with buildings reaching into a sky filled with glowing cosmic dust. She is silhouetted against the luminous, multi-hued sky. The style is inspired by the Pre-Raphaelite Brotherhood's romanticism and detailed artistry, with a touch of impressionistic light and color.
