Vintage Qipao Mother-Daughter Portrait

Based on the photos of two real women uploaded by the user, generate a 2×2 four-grid mother-daughter portrait collage, themed "Qipao Vintage Style Mother-Daughter Portrait."

Character Settings:
Young woman is a daughter, age [{argument name="daughter's age" default="28"}] years; Older women are mothers, with age [{argument name="mother's age" default="56"}] years old. Please strictly preserve the true identity features of both individuals, including face shape, facial proportions, eyes, nose, lips, skin tone, sense of age, hairstyle basics, and overall temperament. Mom retains a natural sense of maturity and slight signs of aging; nasolabial folds are very shallow, not too heavy, and not completely worn off. The daughter maintains her youthful, natural, and delicate features. In all four small pictures, it must be clear that they look like the same real mother and daughter. 

Overall style:
Vintage Oriental qipao photo shoots—quiet, dignified, gentle, with the vibe of a mother-daughter commemorative photoshoot. The image has a slight film feel and a subtle oil painting quality, with an overall realistic photographic texture—refined yet natural.

Clothing and Hairstyle:
Mom wears traditional qipaos in low-saturation colors like light blue-gray, lake blue, gray-blue, and dark green; My daughter wore a modified qipao in navy blue, navy blue, and black-blue colors that coordinated and complemented each other. Their outfits belong to the same visual system—dignified and appropriate, without being overly sexy. The hairstyle is naturally tailored to the original hair length, overall neat and with a Chinese-style hairstyle; Long hair can be styled in a low bun, low bun, or gently styled down; short hair can be styled with a side part, behind-the-ear gathering, or vintage short hairstyle.

Background and Texture:
The background is gray-green, blue-gray, or blue-gray vintage studio shoot backdrops, which can incorporate subtle canvas textures, floral branches, or woody Chinese elements. Use soft studio lighting for low-saturation, high-end, detailed, and realistic images. Avoid excessive skin smoothing, fake faces, watermarks, or logos.

Display format:
Generate a 2×2 quad-grid puzzle. The four small images belong to the same photo set, each in a 3:4 vertical composition. The style, clothing system, and background color scheme are consistent, but expressions, angles, poses, shots, and interaction methods should naturally and diversely. 

Four-panel content suggestion:
1. A formal half-length mother-daughter photo, the two lean close and look at the camera, looking dignified and gentle.
2. Close-up of intimate interaction: the daughter gently approaches from behind or from the side, placing one hand on her mother's shoulder, and the two exchange natural eye contact.
3. Combining sitting and standing in the middle setting: the mother sits on a wooden chair, and the daughter stands behind or beside her, highlighting the layered mother-daughter relationship.
4. Complete duo portraits showcasing the overall qipao look and the gentle and dignified mother-daughter temperament.

Please emphasize the following:
The four grids are unified but not duplicated; The mother-daughter relationship is naturally close; Mothers shouldn't overly rejuvenate or look older; Don't over-lose weight; Don't want to be an internet celebrity; Don't want cheap studio style.
