Use the uploaded authorized portrait as the character reference. Create a high-end photo-studio 2x2 grid portrait in a square 1:1 composition. Keep the same adult person recognizable across all four panels while adapting hairstyle, outfit, makeup, and pose to each theme. Use clean fashion-magazine styling, bright ring-light illumination, an 85mm portrait-lens feel, shallow depth of field, crisp makeup detail, and polished studio retouching.
Top-left panel, navy-blue background: the person wears a navy uniform-style dress with gold buttons, vintage curled hair, a blue beret, and pearl earrings. They hold a large upper-left puzzle piece with the number "20" and move it toward the center. Their eyes focus on the central puzzle area, with a serious expression and a slight smile. The background has navy stripes, anchor motifs, and the Chinese phrase "扬帆新年".
Top-right panel, cherry-blossom pink background: the same person wears a pink lace dress, pearl necklace, princess-like hairstyle, pink rose hair clip, and crystal earrings. They hold the upper-right puzzle piece with the number "26" and move it toward the center to connect with the first piece. Their gaze is focused on the puzzle seam, with an attentive and expectant expression and a slight forward lean. The background includes pink cherry blossoms, butterflies, petals, and the Chinese phrase "美丽相遇".
Bottom-left panel, mint-green background: the same person wears a mint-green cotton-linen dress in a natural artistic style, with long natural hair, a green headband, and wooden earrings. They hold a lower-left puzzle piece with the Chinese text "元旦" and move it upward to connect with the top-left piece. Their gaze is on the puzzle, with a serious expression and gently pressed lips. The background includes green plants, sprouts, leaves, and the Chinese phrase "希望生长".
Bottom-right panel, lemon-yellow background: the same person wears a yellow sunflower-pattern dress and a braid tied with a yellow bow. They push the final lower-right puzzle piece with the Chinese text "快乐" into place to complete the puzzle. They tilt their head back, look at the completed puzzle, and smile with a joyful sense of success. The center bursts with golden light and confetti. The background includes a yellow sun, smile icons, sunflowers, and the Chinese phrase "圆满成功".
The four puzzle pieces converge from the corners and form the complete central message "2026 元旦快乐". Keep all text large, intentional, and integrated into the greeting-card design.
