Well, it looks like you got some of the basics down, that's good.
However, you need to work on the following techniques:
The blur was nice, but there was no easing, easing would have made the animation 10x better.
Some of the movements only had one or two joints moving, and that's called stiffness. Try to move as many joints as possible/necessary to reduce this.
Because of this, I'd say med beginner, but you've got (most of) the basics down.
Also, the shooting guy in the gun animation needed a better reaction to the gun.
