Anime portrait poster, dreamy and elegant

Goal: Create a vertical mobile anime promotional poster for , themed around and luxury gems. Canvas: high-aspect-ratio smartphone format, 9:16, full-bleed illustration, with a dark promotional footer mask at the bottom. Subject: A fantasy anime close-up portrait of an elegant young woman, bust shot, centered and facing forward. Her face is mostly obscured by a centered large square privacy mask, which presents a soft gradient block transitioning from gray-pink on the left to lavender blue on the right. Visible details include long flowing light-colored hair (white, pink, lavender, and pale blue), glossy strands around her shoulders, fair skin, and a small mouth visible below the mask. Clothing & accessories: She wears an ornate silver-white jeweled headpiece, like a crown or halo with filigree and blue gems. Pin a rainbow rose on the left side of her hair, with petals containing five colors: red, yellow, green, blue, and purple. Her neck is covered with delicate crystal lace jewelry, silver filigree, pearls, and blue teardrop gems; at the center of her chest is a huge bright blue teardrop pendant, with a smaller diamond-shaped blue pendant hanging below. Her dress is light, delicate, and wedding-dress-like, adorned with translucent lace, shimmering highlights, and gem-like embroidery. Foreground & background: Use a soft dreamy pastel fantasy background with vertical stained-glass-like beams of pink, yellow, cyan, and purple. Add 1 red rose in the lower-left foreground, partially covering the dress. Keep the illustration highly refined, bright, romantic, and richly detailed, with an ethereal manga style and glossy digital painting texture. Text & promotional mask: Add faint white Japanese text near the top, reading . At the bottom, place a black-to-transparent gradient footer containing 4 promotional elements: 1 red chat emoji icon at the far left, 1 white brand logo text (with "Club" in bold), 1 brief Japanese call-to-action text , and a black-and-white QR code inside a white rounded square at the lower right. Constraints: Keep the square mask covering the face, ensure all text is clearly legible, do not add extra characters, include a total of 2 roses, and maintain a refined vertical social media advertising composition.
