Great work man! Awesome! But I think I remember seeing something like this somewhere before. Not exactly like this, but similar movement. It also had three points of contact with the ground. Were you inspired by something like that?
Nope, I did this with no references whatsoever. It was actually an assignment from an effects animation course being taught by ex-disney effects animator Adam Phillips (www.bitey.com). Perhaps, if you saw something similar and it was recently, maybe it was by another person in the course!
