Not bad =)... the main thing i think hes lacking is a lot more movment... You have all the poses there but he still seems a bit stiff. For example when he first jumps he doesn't really lean down to get momentum for the jump hes doing try and make that pose a bit more pronounced.
Also try and speed some of the moments up a bit using the curve editor.
