Your work is really impressive. Just a couple of observations: The animation is looking great, however, he seems to thrusting his shoulders forward and it sort of looks unnatural.
I am curious as to how he will turn his head. His horns (which are kickass btw) are so huge and placed so that physically it looks like it would be impossible.
Just a couple obsevations, you are obviously a very talented individual so please dont think Im trying to be a jerk 
Would love to see some more of him animated
Cheers
