You've done a good job with making it smooth with the many frames and high fps (frames per second) so good job there. One thing which could use improvement is your foot placement. If the cowboy was supposed to land then his feet shouldn't have been sliding all over the place like they did. Anyway, would like to see more from you.
The part where the cowboy falls and bends over just isn't right bro, you should make the foot bend when he bends like that... Because his legs where very stiff when he fell... Nice animation, but could use some more work
