It's sad that I haven't seen anything come out of this series. It certainly looks awesome! I think this is better than the first one, because it's more clear. We get a better understanding of what's going on. Granted, I'm still not quite sure myself. The Bowser like guy is probably still my favorite.
I love how they are all so unique. The colors have great diversity too. I'm not even sure what most of these guys are even supposed to be. The gray guy looks like just some metal thing. You have a great background too.
