Not bad bud.. you have all the motions happening which look good, i would suggest trying to snap up some of the moments a bit more. Like speed some of the areas up. Right now some of his motion looks like he a bit floaty. You can do most of that tweaking in the graph editor..
Took me a bit to stop haivng my characters look a bit floaty as well, comes with time.
Keep it up mate=)
