Your animation is fluid, and your effects (everything - the fire, lightning, water) are so vivid and beautiful.
Alone, awesome, but you integrated it all so well, including the environment (really sweet "painted" backgrounds) to make it incredible. Also major kudos for mastering your "camera" - the constant motion and varied perspectives made it so cinematic.
What also made it feel even more cinematic was your mastery of your sound. Really well mixed and married to your animation. The tone of the visuals and audio were just so in sync...
...damn dude. Awesome work.
