great!
i really like how you've taken this series in the exact opposite direction of the mainstream stick fight animations, it's incredible refreshing and i enjoyed watching every second of it
now, onto the criticism, some of the motions felt disjointed, and i would recommend increasing your frame rate to get those nice smooth movements that look so good on stick men (you can still do the crazy fast action with high frame rate)
in addition to this, at the point where he was being hit by the pivot man, it didn't look like he was recoiling with enough force, as he was only slowly knocked back about 1 step, just make him sway more and it would look much more natural
and as has been said before, need to be longer, but aside from my petty gripes, I enjoyed it very much, 5/5, 9/10
and i am going to watch every one in the future, keep up the amazing work :D
