Celestial Blue Anime Girl Floating

A full-body anime illustration depicts a dreamlike starry-sky girl floating diagonally against a pure white background, seemingly weightless in open air, presented from a bird's-eye view. She possesses extremely long, flowing {argument name="hair color" default="Deep Navy Blue"} Her hair, like an elegant ribbon, cascades around her body, shimmering with highlights, stray strands, and adorned with a star-shaped hair ornament on one side of her head. Her face is softly blurred, the composition emphasizing her delicate posture, attire, and the surrounding magical atmosphere. She wears a richly detailed white and blue sailor-style fantasy dress with semi-transparent layered sleeves, ruffled lace, shimmering lace, and lightweight fabric, adorned with a large star-shaped crystal brooch at the chest. The dress contains five clearly visible elements: a short, ruffled dress, a sailor collar and choker, semi-transparent split sleeves or draped chiffon layers, one leg clad in white knee-high stockings, and the other in dark blue star-patterned knee-high stockings with matching garters. She is barefoot, her feet clearly visible. Her posture is graceful and ethereal: one arm outstretched with an open palm, the other placed on her chest, one leg straight, the other slightly bent. Surrounded by luminous constellation patterns in cool blue tones, including six striking pentagrams scattered around her, countless tiny starlight, circular watercolor-style swirls, floating bubbles, and ornate crescent-shaped filigree encircling the canvas. The color scheme uses ice blue, cobalt blue, indigo, and white, complemented by shimmering sequins, soft translucent overlays, clean lines, and a light, ethereal halo. The overall atmosphere is magical, elegant, ethereal, and serene, like a star maiden suspended beneath a winter night sky, presented on a pure white canvas.
