Bob:

The girl face palming at the end is a nice touch

The guy lip syncing needs more animation. He doesn't say 'personal' properly

Charlotte:

The woman's turn looks a bit stiff, maybe try adding some inbetweens in there

Jason:

The animation looks pretty good, a little stiff at times but overall good. The biggest thing that took me out of the animation was the head. Try playing a little more with the head and eye movements, they look a little stiff. Other than that it looks pretty good
