I made this comment in beginner's chat but I suppose I'll copy it here for you to keep track of.
The first man has some strange movement. It is very fluid however, and you have a good sense of the basics for pivot. The awkward pose in the first part is really distracting though, and it draws from the animation. When he meets the ground I understand you want to keep him moving, but it sort of defies physics the way he's moving, and doesn't make sense. The focal point of the animation, however, the man running and kicking, is very well done, you clearly aren't new to the program. Keep that up, and you'll be up in the ranks in no time. :)
