Pretty good. Some posing issues, though...
I think this is pretty well done, especially considering that this is more-or-less a one-man job compared to some of the lousy modern day cartoons that the professionals are doing for the big companies.
Animation is fluid, action is good. The start was a little slow though (I mean literally, like at the start when Tricky was running, he seemed to be running a little too slowly).
Main issue I have was with some of the posing, however. At some points, the characters' two-handed grip on their respective weapons looks a bit off, almost like the arms are twisted. Add that to the fact that they do not actually HAVE arms to help the imagination, it does seem to detract from the overall polish of the final product.
Perfectly fine apart from that, however. Great job!
