Update

I have updated the animation and the character model based on feedback given by peers.

Character model

I have made the cheekbone seem a bit more natural and blend with the rest of the face as before it was looking very edgy. I have also made the mouth in a higher position because the mouth was too much into the chin. If I change something about this model, I would have changed the hands slightly to make them seem a bit more realistic. Also I would have merged the ears better as they do not appear to be in the correct form in my opinion.

Animation
I have updated the animations, The first thing I changed was the foot glitch that happened in the post box animation. The facepalm was also too slow in the first animation, thus I edited it in a manner which fits the motion. In the piano lip sync animation, I played around with the lip sync for a bit to make it a bit more in sync with the audio as before in some parts, it seems rather off. Each of these animations also has a bit more dynamics with the fingers. In the previous animation show reel, the fingers were pretty much motionless throughout the animations unless they were needed.
