Great work, can't wait to see more
This has the potential to become a huge series. You have a very strong sense of design. The characters look great, and they are animated very well. The action scenes are very well done, too.
If I could make a suggestion- the dialouge is not bad at all, and it was almost all very well acted. Except for one voice. There was one guy who seemed very wooden and was very obviously reading right from the script. I am not saying that that person could not improve, but you would do well to have them rehearse a bit before recording. Try some method acting, it helps sometime.
Again, well done. Can't wait to see more.
