Looks pretty good...
But why a preview? Everyone does previews and trailers and teasers and that kind of crap. I understand if it's a really lengthy project that goes on for months and you want some feedback in the early stages, but I don't think it was really necessary here.
The animation was pretty good, and the effects were nicely animated and so on. It looked like something that would make a really cool game. But with so many stick fighter movies out there and more coming out every day, I just don't know....
