First try
While I didn't like this movie much, I will have to give you credit for it being your first try. There's the fact that you used that awesome music and showed an extended version of it that really won me over. Let me just say welcome to Newgrounds! There's a lot of room for improvement though. First, you need to make your work longer and have more action. Second, there should be a bit better animation like with more emphasis on color and it wouldn't be nice to throw in some voice work. I'm happy to join!
