In the main image (the one with the car and two people), replace the man's face with the face from the reference photo of the man holding the baby, ensuring an exact likeness. Similarly, replace the woman's face with the face from the reference photo of the woman in the white polo shirt, making it identical to the original. Keep everything else in the main image—bodies, clothes, car, background—unchanged. The lighting on the new faces must match the sunny outdoor environment.
