Aquarius Sea Priestess Poster

Using the provided reference image as the character base, transform the portrait into a vertical fantasy poster of {character_name}, an elegant sea-god priestess. Keep the same ethereal pale-haired woman and upward over-the-shoulder gaze, but change her into a full-body/three-quarter composition in an ancient celestial water temple. Add exactly these new elements: 1 ornate crystal-and-gold staff topped with a glowing blue orb, 2 tall ruined classical columns framing the scene, 1 large luminous crescent/ring arc across the night sky, flowing water and ice-like translucent fabric swirling around her, blue gemstone jewelry and chains in her hair and dress, and sparkling star effects throughout. Outfit transformation: replace the dark ruffled dress with a sheer white goddess gown decorated with gold filigree and blue gemstones, with flowing translucent sleeves and fabric ribbons. Give her long windblown platinum-white hair with jeweled head chains, and change the earrings to dangling blue crystal earrings. Text: add a refined gold Japanese title at the top in two centered lines: {top_title_line} and {bottom_title_line}, with delicate ornamental divider flourishes. Add a small elegant gold signature at the lower right reading {signature}. Style: luminous high-detail anime fantasy illustration, icy blue and silver palette, celestial ocean magic, glossy highlights, soft divine backlight, dramatic vertical poster composition. Avoid modern objects, extra characters, or cluttered text.
