Nice work, I know how much work goes into an animation like this. Awesome enviornments, I like how you did a nice job of making the facility seem huge. Maybe toss on some grungy textures to it, sense its an abandoned facility it shouldnt be spotless. Rust, dust, grease smears, oil leaks, etc. I liked the guy actually. and nice camera work looking through his helmet. Only suggestion i have, and others have said it to, his walk/run cycle were a bit rough. He covered a tad too much distance for the run you had for him and he didnt transfer his weight at all. Even robots have to shift weight from leg to leg to distribute the weight of the body. Now some will argue that he could be in space so gravity is different but even then the arch of his run was a little flat for that. But that just comes with practice and constant observation. Like I said before, over all nice work, and im looking forward to what you do next!
