Icy Xianxia Princess Portrait

Create a vertical cinematic ancient Chinese fantasy portrait of a noble princess in an icy palace, shown from mid-thigh to head in a centered frontal composition. The subject is {argument name="character gender" default="a young woman"} with long flowing {argument name="hair color" default="black hair"}, wearing an ethereal {argument name="robe color" default="white and pale ice-blue"} hanfu-inspired ceremonial gown with translucent wide sleeves, layered silk, delicate embroidery, silver filigree, pearl chains, crystal drops, and ornate beaded shoulder drapes. Give her an elaborate silver phoenix crown and hair ornaments with many dangling pearls, crystals, floral metalwork, and thin chains framing both sides of the face. The expression should be serene and regal, with refined beauty, but keep the face unobstructed and natural. The background is a grand frozen palace hall with tall carved columns, pale stone reliefs, soft mist, floating snow or dust particles, and cool blue-gray light. Use shallow depth of field, luminous backlighting, high-detail jewelry, sparkling highlights, soft volumetric haze, elegant xianxia costume-drama styling, ultra-realistic fashion photography, 9:16 vertical aspect ratio. Avoid modern objects, text, logos, harsh colors, exaggerated anatomy, and visible facial covering.
