Add the person from the first reference photo into the group photo (second image).

Place them naturally in the scene — match scale, perspective, lighting direction, shadow softness, color grade, and depth of field exactly. Pick a believable position in the group (next to a specific person you can describe) and have them face the camera with a natural smile that matches the group's mood. Use the same face, identity, age, skin tone, hairstyle from the first reference. Add a realistic outfit appropriate for the occasion in the group photo. Make sure feet are grounded and the body sits correctly in the perspective plane.

Keep all other people, expressions, poses, outfits, and background exactly the same. Output must look like a single original photograph where everyone was present. Avoid: floating subject, wrong scale, mismatched lighting, missing shadow, distorted face, extra fingers, copy-paste look, watermark, text.
