Decent.
It looks very Dan Paladin inspired, which isn't a bad thing, because it was also pretty original. One thing I did like a lot, was how you zoomed in on the characters faces, and you could see all the details on them. It showed you have a little more drawing ability then little walking blobs. Now the animation itself could use some work. It was very sketchy frame by frame, which seemed to fit with the style, but could use some touching up. Overall, I liked it, but it needs some work done to it to make it a real gem here on Newgrounds. Try adding actual punch animations instead of just the tween of one character punching, then the other flying backward. It's good to use once in awhile, but not every time something happens, it comes off as cheesy. Also, when you do decide to animate something like that, don't make them silouhetes, it's unnecessary and it seems like your just being lazy, but I've done the same thing, so I can sympathize. Overall, it's a good flash, keep up the good work. Best of Luck.
