Retro New Chinese Qipao Portrait Grid

Based on user-uploaded real photos, a 2x2 grid of "New Chinese Retro Mother Portraits" is generated. All four sub-images must depict the same woman, strictly preserving her face shape, facial proportions, eyes, nose, lips, skin tone, etc.{argument name="age feel" default="50-65 years old"} Basic hairstyle, body shape, and overall temperament. It is strictly forbidden to alter facial features to resemble someone else's, to overly youthful appearance, to adopt a "web celebrity" look, or to excessively smooth skin. The overall style is a modern Chinese-style retro cheongsam studio portrait. The image should be refined and natural, presenting a traditional studio feel, a retro Chinese-style magazine-style feel, with a slight film grain and a soft oil painting texture. Clothing should be an elegant modified cheongsam or a modern Chinese-style suit; color is optional.{argument name="clothing colors" default="Dark green, navy blue, burgundy, pearl white, or lotus root pink"} Props may include folding fans, magnolia flowers, orchids, pearl necklaces, wooden chairs, and vases. Background color scheme must be consistent and optional.{argument name="background color" default="Dark green, black, hazy blue, deep purple, retro red, or warm caramel."} The four photos should differ in pose (full-body seated, half-body holding flowers, side profile, and front half-body), expression, and angle, while maintaining consistency in lighting, clothing, and scene style. The skin should have a natural texture, conveying a moderate sense of age and maturity. Avoid cheap studio-style photos, heavy makeup, or overly exaggerated styles.
