Double Watercolor Reverie

Strictly based on the uploaded reference photo, lock in the same main subject's identity, keeping head features, facial structure, bone proportions, face shape and contour, original hairstyle, skin tone, apparent age and body type consistent; an ultra-realistic birthday fashion portrait poster, vertical 9:16, portrait photography fused with graphic design, with a phone-wallpaper feel.\nUse a two-layer portrait layout: at the upper left, an enlarged, low-opacity half-length background portrait, body turned slightly, head turned to the left; at the lower right, the clear main half-length portrait, also looking to the left, with a quiet, confident, stylish pose. The two figures must be the same identity, with facial proportions, hairstyle, skin tone, body type, clothing and accessories completely identical, with no face mixing, merging or change of age.\nBoth figures wear black narrow-frame sunglasses, a light-colored flower tucked at the side of the head, and a loose black shirt; the sunglasses, earring, flower, collar and fabric folds are clear and consistent. The clear main portrait has sharp face and clothing details, while the upper-left background portrait has reduced opacity and softened edges, yet the figure's outline and the same look can still be recognized.\nThe background uses aged paper in warm beige, light coffee and milk-tea tones, with paper fibers, slight creases and a vintage print texture; large brown-coffee watercolor splashes, spatters, washes and irregular edges are layered over it, creating a soft, vintage birthday-poster mood. At the upper right, lay out the text accurately in hierarchy: small capital letters “HAPPY”, below it large black handwritten script “Birthday”, below that black serif type “stylish”, and beside or below it golden-brown handwritten script “pic”. English spelling is accurate and the letters are clear; do not generate extra text, gibberish or distorted characters.\nSoft warm light evenly illuminates the main portrait at the lower right, the skin keeps its real texture, and the black shirt still shows tonal layers; the overall background is low-contrast, with a slight paper-fading and vintage-print feel. A premium birthday fashion poster, a warm beige vintage design, combining realistic photography with watercolor graphic art.\n
