Anime Sky Fantasy Key Visual

A polished anime fantasy key visual in a wide cinematic composition, showing a serene young heroine on the right half of the frame against a vast sky kingdom. She is a beautiful teenage girl with {argument name="hair color" default="long silver-white"} hair, large {argument name="eye color" default="clear blue"} eyes, pale skin, and a calm, slightly wistful smile as she turns her head back toward the viewer over her shoulder. Her hair is very long and windblown, with soft layered bangs and a side ornament: 1 blue crystal hairpiece with silver filigree and trailing blue ribbons. She wears an elegant white-and-blue fantasy outfit with 4 visible main garment elements: 1 white hooded cape draped over her shoulders, 1 deep blue inner dress or tunic, 1 ornate silver armored shoulder and upper sleeve section with engraved details, and 1 blue gemstone brooch set at the chest. The background is a luminous high-altitude fantasy world filled with bright clouds, blue sky, and floating islands; include 3 prominent floating architectural elements: 1 large central floating landmass with castle structures, 1 tall narrow spire emerging from the lower left clouds, and 1 distant towered island near the center. In the upper left sky, depict 1 majestic white dragon with wings spread, flying diagonally above the title area. Add a large stylized Japanese title on the left side with metallic silver and glowing blue typography, reading {argument name="main title" default="白竜の翼と青き記憶"}, with decorative wing motifs integrated into the lettering. Beneath it, add 2 smaller lines of subtitle text in Japanese, centered left: {argument name="episode label" default="Episode 1"} and {argument name="episode subtitle" default="白銀の空隙"}. Scatter a few white glowing feathers or petals in the air. Use a cool palette of white, silver, and luminous azure, highly detailed linework, soft cel shading, crisp highlights, ethereal lighting, and the feel of a premium light novel cover or fantasy anime promotional poster.
