The level of his feet gets gradually lower. Not sure if that's intentional. Some people would try to synchronise the hands with the feet too. Otherwise not bad.
yes indeed...he walks lower and lower...i have a problem with that if i am making him walk under the line and not directly on it...and when he punches...the second punch looks like its the same arm...normally a person would punch with different arms if speed was the factor...but if it was strength, yes i guess 1 arm would work...
