A three-quarter view medium shot of a graceful elf woman standing on the ornate stone terrace of a grand classical music hall at night. She has long, flowing silver-white hair with straight bangs and distinctive heterochromia, featuring one aqua blue eye and one red-orange eye. She wears an elegant 1920s-style black flapper dress with sleeveless refined design, layered fringes, and subtle silver embroidery of musical notes and stars, accessorized with a pearl necklace, drop earrings, and a small silver star hair clip. She leans gently against a carved stone railing, one arm resting on the stone while the other is placed softly near her chest, looking toward the viewer with a peaceful, blushing smile. Behind her, tall columns and glowing windows of the music hall contrast with a deep navy sky, a crescent moon, and a distant golden city skyline. Subtle, glowing musical notes and sparkling particles float in the air. The atmosphere is romantic and dreamlike, illuminated by warm golden rim lighting and soft moonlight, rendered in a painterly anime style with a cool teal-blue and gold palette.
