Girl anime poster, starry sky, cool tones, elegant

A highly dramatic Japanese fantasy anime movie poster, in a vertical single-sheet composition. At the center is a beautiful girl with extremely long flowing silver-white hair, sparkling golden eyes and a calm, captivating smile, reaching one hand out toward the viewer. She wears a black-and-white starry-sky gown with a fitted corseted bodice, a white chest panel, black ribbon lacing at the front, black detached sleeves with soft white ruffles, a black waist belt, multi-layered skirts decorated with 3 golden crescent moon ornaments, and a black choker with a golden crescent moon pendant around her neck. Near her bangs she also wears 1 golden crescent moon hair clip. The background is a brilliant night sky filled with stars, accompanied by nebula-like clouds, with a giant eclipse halo hanging overhead and 3 floating crescent moon ring effects surrounding the strands of hair on the left. The background shows an ornate fantasy city with towering gothic palace architecture, spires, observatory-like structures, and twinkling windows, all bathed in cold moonlight. The overall palette uses rich tones of deep indigo, violet, midnight blue, silver, and gold, accented with sparkles, magical particles, rim light, and glossy highlights, presenting a texture-rich, modern anime-style painted poster effect.
