My general note is to be snappier, don't slow morph shapes between the expressions. Change the eyes from open to frustrated like a hard cut and animate an overshoot to the eyeballs at the final state, as an example. Also try animating the body of the cups, that could help making the reactions more interesting. This kind of trickery will help gives it a bit more character and improve the animation overall.
gotcha! good note, i appreciate it. I'll try to make some tweaks and add more movement
