Use of 3D to Animate Heads in After Effects
Here is another approach to animating heads for animation in After Effects.
motion track head movement to null 1
make all objects 3D
make new null, position as pivot point, name "rotator"
add expressions to "ratator" X Rotation and Y Rotation
arange objects on Z plane
"rotator" X Rotation expression:
0-this Comp.layer(null 1).transform.position[0]
"rotator" Y Rotation expression:
0-thisComp.layer(null 1).transform.position[1]
