Epic Desert Couture Heroine

Create a vertical 9:16 large-format cinematic fashion portrait of character_name as the heroine of an epic desert fantasy film, standing powerfully on the crest of a high sand dune at sunset. Her face is intentionally soft, indistinct, and featureless, with the emphasis on silhouette, posture, costume, and atmosphere rather than facial detail. She has very long pale blonde hair blown sideways by strong wind, and she wears a dramatic couture desert gown in dress_colors: layered translucent chiffon, flowing panels, leather-like sculptural straps, fitted bodice, asymmetrical drapery, and long ribbons streaming far into the air. She holds one long staff or banner pole diagonally across her body, with a pale fabric streamer whipping behind her, while her other hand rests confidently on her hip. The environment is a vast realistic desert with endless rippled dunes, deep shadowed valleys, distant dark mountain silhouettes, airborne dust, and glowing atmospheric perspective. Place the low sun near the right horizon, producing intense golden rim light, sun flare rays, long dramatic shadows, and illuminated dust particles around the figure and dress. Camera angle is slightly below eye level, making her look heroic and commanding despite the enormous landscape. Use IMAX-scale cinematic composition, extreme environmental realism, high-detail sand texture, windblown fabric motion, volumetric golden haze, warm orange and rose sunset sky, deep blue-purple shadows, and premium epic movie color grading. No text, no watermark, no extra people, no modern objects.
