Er, it's really messy and grainy. Put it in your post and use imgzoom if this is actually pixel art; I really can't tell right now whether it's pixel-precise, but it doesn't look like it. Also, the angel thing is hard to make out because of the fire everywhere, which should be less evenly distributed and flicker and sway more instead of just scrolling up. It's also way too busy; parts of it look like a wall of noise at the moment, particularly in the middle of the angel thing.
Did you make everything in this from scratch, or did you just animate it?
