Plenty of good crits goin' around, so i'll offer my measly twocents.
This animation should run much slower. right now, as mentioned, he seems to be out of breath. And also he seems panicked, unorganized, and scared. A dragon should be cool, in control, and calm. Slow this down, and change the eyes to look much less scared. And the mouth too, for that matter. I would also stay away from animating a piece this big, but its your piece and your time.
