Good practice
I was a little disappointed, around the middle somewhere there was one you did with a more human-shaped character than a simple stick figure, I was hoping it would be a trend towards turning the things you had learned towards animating more complex characters.
I think that in particular the impact animations where you showed the energy transference in the circles showed that you have the talent and ability to make some very nice smooth animations, I think that you're limiting yourself too much with just the stick figure work. I also feel that all the "WTF"s detract from it rather than adding to it in any way.
So overall you have nice smooth physics, I'd like to see more complex characters and better dialogue.
