Hmmm
Frankly, this looks like a highly modded Mugen game(yes, I do realize evilryu is a mugen character, I prefer both him and evil ken xd)
Too little focus on details, like background(e.g. destructable terrain), repeatable sounds, too much focus on 2D, rather than pseudo-3D. In other words, make the camera less static.
Music was fine, but it seems to be just put in there, it doesn't seem to go in sync with the battle.
All those things summed up with unrefined bits of animation here and there make up for an above-average, but still not quite satisfactory score.
Cheers.
