Pretty good! I like it.
I enjoyed the intricate characters, and the graphically smooth fighting was very good. The game and battle locations had a certain flair to them which was also good. The music varied quite a bit, but became a little monotenus after a while. The different faces for each character helps a lot with the interactivity, but was the only humorous thing there. Overall, I loved it, and only have several suggestions.
You should add more special moves.
You should add unLOCKables.
You should make more stages.
I salute you as a genius flash artist!
