I think this is really good.
I dont see why so many people criticise your movies so much.
I watched all of them and i think they're all very decent.
Nice Shading, Nice Animation (good mixture of FBF and tweening) Good Classic Fight Sounds (although i think there should be more ambient noises such as nature and crowds)
I like fighting games as much as the next guy and i dont really mind seeing many fighters thrown around into the mix.
I dont really care that you trace faces either. (as long as the animation is good which it is)
Only things you should improve on in my opinion is..
Voice Work and Lip Syncing.
great work! take my advice. and keeping makin' more!
