the models are all looking really nice and coming in great... though the spotlight on Chem feels... a little harsh. would definitely suggest turning it up a bit but widening the area to make it "spread out" a little softer... unless you are going for a spotlight, in that case it needs to the end of the circle more abruptly.
The walking animation looks... off. like, moving feels like it goes slightly off center to begin with, but then with the person always looking at the mouse while moving backwards is weird... perhaps the person should always turn in the direction they are moving instead?
