Please stay to one topic to avoid clutter. Overall, just work on te easing and flow of the animation. That seems to be the most obvious flaw in the animation.
Ummm that black stick was shaky and your movements are kinda slow. So when i watch it its a bit boring ''_" . Also, you should work on 2D animations first before 3D or your animations will be much worse -_- BUT make more animations! i kinda like it!
Yea I agree with Legend. That timing was terrible, no offense. You should work on other stuff before you do things like this. Maybe sometime in the near future you'll be able to do this sorta stuff.
