Wow.
I've loved this series from a far for a while. It has some of the most unique and entertaining fight coreography I've ever seen. The highlight of this one is most definitely the final confrontation with Smoke. I've always been fond of gun/sword battles, no matter how implausible they may be in real life. Just the notion of two characters with largely different fighting styles duking it out evenly matched is a thing of beauty to an action fan. Keep up the good work.
My only criticism? I think maybe the art style needs a bit of revision. Just because, it's hard to delight in the rabbit death when you make them look so frickin' cute.
