Wow. Very good for your first try.
As most people would expect, I though I would see some shapes or some terribly draw character being thrown around a colorless background with some garbled sound effects.
....Instead, I get this very decient animation. I really like your graphics. They are very artistic and well done, don't change them. I believe your trying to send a message but I don't know what it is exactely. You may want to up your frame rate i looked like it was running on 12 fps but thats okay for begginers.
Your music choice fit with how everything was done. My only problem with it was how it looped. Not a very good loop but I got over it soon enough.
In conclusion I can only congraulate you on making your first piece of animation worth while.
