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. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
