add person to group photo

Please add the woman from the provided portrait into the group photo.
Place her above the matriarch (front center, older woman) in the open space behind her.

Important details:
— Match her face size to surrounding people
— Flip her slightly so she leans toward the man on her left (her husband)
— Match lighting, color, and skin tone to the group photo (outdoor daylight)
— Blend edges and shadows naturally so she looks like she was there
— Do NOT alter any other faces

This is a sentimental Mother’s Day gift, so realism is very important.
