I showed the classmates the last ticking test for the mime animation and they agreed it needed to be more subtle.
Kristian pointed out that the face would be the selling point of this part of the animation.
The character is currently looking up to the left, imagining what it could be inside the box. He suggested what if the character squints his eyes a bit and perhaps lifted a part of his lip to look like he's really concentrating on what he's listening to.
I really liked this idea so will definitely try it out!
