Celestial Guardian in Floating Reverie

9:16 vertical, ultra-detailed 3D CG oriental fantasy heroine poster, full-body portrait of a clearly adult young celestial protagonist, visual age around 20–24, rendered in polished anime-realism with semi-realistic facial modeling and premium virtual character finish. The mood is sacred, ethereal, elegant, dreamy, and serene, evoking the mystery of a starborn goddess and a sky-realm princess. High-completion 3D character render, not flat illustration, with exquisite modeling, realistic material response, cinematic lighting, flowing costume dynamics, and the refined texture of a luxury collectible fantasy poster. The sole subject is Lady Yunastra Vale, a fictional sky-temple guardian with a soft East-Asian-inspired fantasy beauty: delicate oval face, smooth refined contours, fair translucent skin with gentle subsurface glow, lightly closed eyes, long lashes, graceful nose bridge, and small peach-pink lips. Her expression is calm, healing, quiet, and otherworldly, as if drifting peacefully through the upper heavens. Her hair is short, airy, and romantic in creamy champagne-blonde, with soft natural curls, feather-light volume, and finely modeled strands catching subtle golden highlights. The ends drift weightlessly in the wind, enhancing the sensation of floating high above the world. She wears a high-precision oriental fantasy ceremonial dress in white, ice blue, deep royal navy, and restrained gold embroidery. The upper portion is an off-shoulder white bodice with lace, chiffon, layered ruffles, sapphire-toned bow accents, and an intricate lace-up corset structure across the chest. A midnight-blue waist bodice adds structure and elegant contrast. The skirt is a layered short formal dress of white and pale blue translucent fabrics, edged with ruffles and delicate embroidery, with gauzy panels and long navy streamers trailing from the waist and back. On her feet are deep blue heels with ribbon bows tied at the ankles, refined and noble. Her pose is essential: she is not standing, but suspended in a slightly reclined, diagonal floating posture high in the sky, as if weightless between cloud ocean and cosmos. Her head rests slightly higher than the rest of her body, back and waist gently arched, one leg softly bent, the other naturally extended downward, creating a graceful elongated curve. Hair, skirt, ribbons, and gauze drift freely in zero gravity. In one hand she carries an ornate ceremonial longsword, its slender blade pointing downward, with a gilded hilt engraved in star motifs and celestial filigree. The composition is centered and singular: only Lady Yunastra Vale appears in frame. The backdrop is a vast dreamlike sky-cosmos panorama with luminous cloud seas, a grand blue atmospheric curve reminiscent of a planetary horizon, deep starfields, distant nebula glow, and scattered points of starlight. White feathers, pale blue ribbons, tiny light fragments, and a few small white birds spiral through the air as decorative accents, preserving an epic sense of depth and holy stillness. Lighting blends radiant high-altitude sunlight with cool cosmic illumination, producing soft clear highlights across her face, hair, dress, legs, and sword. Materials are rendered with realistic PBR fidelity: lustrous silk, translucent chiffon, ornate metallic sword details, glossy fabric sheen, precise embroidery, realistic hair strands, and luminous subsurface skin. White, dark blue, ice blue, and gold dominate the palette. Unreal Engine quality, Octane-style finish, cinematic depth of field, soft bloom, celestial cloudscape, ultra-detailed, sacred, graceful, and breathtaking.
