Any constructive criticism will do.
It's two random demons (one of them using the Fist of the Mortal Flame technique) in the Pseudospace (dimensional portal between the Living and Demon worlds in Yu Yu Hakusho), in front of a broken Kekkai Barrier.
Here's the original I made a while ago. As you can no doubt tell, I've made a few changes since then:
Looks good MV, the flame could use another frame of animation.
The Kekkai Barrier to me, looks better on the smaller one. i think the big one moves alittle too much.
