Add identical twin sister realistic editing

Use my uploaded original image as the sole editing basis for local modification, do not regenerate or redesign the entire screen. Maximize retention of the original person, background, composition, lens distance, perspective, camera angle, light, shadow, tone, spatial structure, and original photography style. Retain the original person herself and her original face, sense of age, hairstyle, hair color, skin tone, body proportions, body type, clothing, position, and main posture; do not swap faces, do not re-beautify, do not change the identity of the original person. Naturally add another woman next to the original person, set as her identical twin sister. The newly added person must be based on the original person herself, maintaining the same face shape, facial structure, sense of age, skin tone, hairstyle, hair color, body type, body proportions, and overall temperament; the two must look like real twins at first glance, not two similar models. Do not simply copy and paste. The newly added person can have very slight changes in head angle, gaze, hand movements, and body orientation to make the twin relationship more real and natural. The two are close together, showing a slight snuggle or a slight hug. Let the newly added person lean gently toward the original person, shoulders close, arms gently resting on the shoulder, upper arm, or side of the waist; movements should be soft, restrained, and natural, no excessive hugging, no exaggerated body movements. The clothing of the newly added person must maintain the same design, cut, material, structure, and style as the original person, only changing the color. Automatically select soft visual complementary colors based on the original clothing color, such as blue corresponding to orange or amber, pink corresponding to mint green, purple corresponding to yellow-green. Complementary colors should be low-saturation, coordinated, and fashionable, not fluorescent or overly eye-catching. The newly added person must completely match the original image's lighting, including main light direction, shadows, skin highlights, hair highlights, clothing reflections, environmental reflections, and grounding shadows. The contact between the two people's arms, shoulders, hair, clothes, and bodies must comply with real physical relationships; no clipping or incorrect overlapping allowed. The final effect should look as if these twins existed in the original scene from the start of the shoot. Maintain a realistic photography feel, natural skin texture, real hair strands, correct human body structure, and real perspective. Avoid anime faces, CGI, plastic skin, copy-paste feel, mirror-image feel, wrong fingers, wrong limbs, body fusion, wrong perspective, major background changes, major clothing style changes, and obvious AI synthesis traces.
