Minecraft Animation Critique

I have been creating Minecraft animations as I learn to use Blender. Thought maybe it would be a good idea to check in with the Blender community to get some feedback and suggestion for improvement. For those that do not know, minecraft is a game, the objects and textures in this animation come directly from the game. What I have done is rig the characters, light the scene, animate and do a little compositing on the light sources.
