Elegant Horned Fantasy Maiden Portrait

An anime fantasy portrait of [an elegant blue-haired fantasy woman], shown from the back in a three-quarter pose, turning her head over her shoulder to gaze at the viewer with calm violet eyes and a soft, distant expression. She has very long, flowing [icy pastel blue] hair with layered wispy bangs, loose windblown strands, one small ahoge on top, and one dark curved horn with subtle crimson striping emerging from the left side of her head. Her refined backless fantasy gown consists of a dark fitted bodice, a white open-backed outer layer with ornate gold trim and embroidered patterns, long detached sleeves fading into translucent blue-violet pointed cuffs, and red-blue ribbons tied at the neck and waist with delicate jewel tassel details drifting in the air. Backlit by soft spring sunlight in a pale stone pavilion with an arched balcony opening behind her and clusters of glowing [pink cherry blossoms] in the upper background. Drifting petals, luminous haze, subtle sparkles, and a dreamy pastel atmosphere. Vertical composition, upper-thigh portrait framing, character placed slightly off-center right with sweeping hair broadly filling the left side. Rendered in a polished ethereal anime illustration style with soft bloom, translucent fabrics, glossy eyes, delicate linework, cool lavender and blue tones, gentle rim light, and painterly background blur.
