What the?
The first thing I'm curious of, is what kind of program is the artist supposed to be using in this movie. Is it linux? Windows? I'm not entirely sure to be honest. As far as your animation skill itself goes, very superb, and yet at the same time your avatar's animations weren't as fluid at times when he moved as he was at other times.
Overall I gave it a 6, good animation, but a little confusing to someone not savvy with computer programs.
