Great
hey, great piece of art there lad!
I like your art, even if its a nudge too much like manga / anime, hope you'll develop a more distinguished, own style soon.
Music fit well and i can understand that you didn't add screams, sword-clashes etc.
even though you could have put in some of those, that would have less volume than the music ( sort of in the background)
how many sheets of papers did you use and how many sheets were there per second? would be interesting to know as i would like to do something like this as well.
