you might want to show it to us in less FPS, and with a pause on the frame where his mouth is closed, so that it looks like he is attacking/yelling etc. Also the outer-left and -right flares are acting spastic...
Not familiar with the original, but you can take some artistic license, I'm sure, and make the spikes look more like fire and less like spikes.The "body" (face) is very cool though.
