Ethereal Blue Wedding Anniversary Poster

Create a vertical, high-resolution wedding anniversary poster with an ethereal and minimalist aesthetic. The background is a soft, misty light blue gradient featuring delicate shadows of tree branches on the left side. In the upper center, place large, elegant serif text reading "10th" in dark navy blue, with a thin red line drawing a heart shape next to it. Below this, write "ANNIVERSARY" in spaced-out capital letters. Further down, include two lines of smaller text: Chinese characters "十年相伴 一生相依" followed by English text "TEN YEARS TOGETHER A LIFETIME WITH YOU", separated by a small rose icon. At the bottom center, display the names "ZHI HAO & YI XUAN" and the date "2014.05.20" in a small, clean font. The main subject is a couple sitting on a smooth, reflective white floor, viewed from behind. The man wears a dark suit and has short black hair; the woman wears a backless white tulle wedding dress with her hair up in a bun adorned with flowers. They are leaning their heads together affectionately. Surround them with sparse, floating pink flower petals and blurred floral arrangements on the floor.
