Mr. wood chopper. :D
I saw the other ones, they are all pretty nice.
It would be nice if he would do all of these actions in locations with different surroundings.
I know that it would take longer to render and some extra modeling, but it would look good.
Like the idle animation were he would stand, I don't know.. on a small island in a middle of nowhere
or in hangar, actually anything could work.
Your modeling and rigging, animation seem good, but you could work on lights a bit.
Anyways, good work. :)
