Also, I spot a lot of problems with even the base mesh and those emotions.  While they are very good for stills, during animation, most of them will look strange, because there's no illusion of muscle movement there, based on the underlying topology.  When her lips are curved, it's simply that.  The rest of her face, the edge loops that are under there, aren't deformed properly to indicate that there's muscle tissue attached to her mouth.  Then once it's deformed into a character, the problem becomes worse, because now the geometry is being pulled in too many directions, and there simply isn't enough detail to go around for all the requirements.  The edge loops aren't representing muscle tone so much as they are there for the many purposes they are needed for to create many different characters, as well as expressions.
