Tender Mini-Me Studio Portrait

Create a premium photorealistic vertical studio portrait of exactly two subjects: an adult young woman and a miniature childlike version of her sitting on her lap. The adult woman is {argument name="adult subject" default="a young South Asian woman"} with warm medium skin, soft natural makeup, thick dark eyebrows, deep brown eyes looking downward with a gentle closed-mouth smile, and {argument name="hair style" default="dark wavy hair loosely tied back in a messy low bun with face-framing strands"}. She wears an oversized plain {argument name="shirt color" default="black"} T-shirt and dark pants, seated in a relaxed pose with one arm down and the other hand resting near her lap. The miniature child is a tiny girl, about doll-sized but fully realistic, sitting cross-legged on the adult's lap, looking up at the adult with a bright affectionate smile; she has matching dark wavy hair, similar facial features, small stud earrings, and wears a muted brown patterned short-sleeve top with matching pants. Include exactly three visible accessories: a delicate thin necklace with a small pearl pendant on the adult, a brown leather-strap wristwatch on the adult's wrist, and small stud earrings on the child. Use a warm beige-brown seamless studio backdrop with subtle texture, golden rim light from the upper right outlining the hair and shoulders, soft diffused key light from the front left, shallow depth of field, realistic skin texture, cinematic color grading, high-end editorial portrait photography, vertical 4:5 composition, adult centered slightly to the right and child positioned lower left on her lap. Keep the mood tender, maternal, intimate, and elegant; no text, no watermark, no extra people, no cartoon styling.
