Trying to keep my character's head from wandering

Hey all!

Hopefully one of you delightful animation space wizards can help me on my quest for enlightenment....
I'm trying to make a character (just a head like an emoji/smiley) stay centered instead of wandering when my head moves on the webcam.
I still want the head to turn but by staying centered, I've managed this once before but can't seem to find the trick here,
aside from of course deleting the "Face" behavior - which isn't ideal and reduces more natural animation options.

Any help would be greatly appreciated,
Thanks!!!
