Work on your voice man.

You're singing in like 500 different keys.

You're flat, you're sharp, and very few times on key. And try to keep the strumming style constant. During the chorus it changed dramatically.
Just try to clean it up

EDIT:

one more thing. Try to keep the tempo constant. You started out nice and slow and by the end of the song it was about 2 times faster than you had started. Try not to rush. Relax. Keep the tempo constant

Exactly the kinda crit I wanted lol. Thanks. I plan on re-doing it all anyways. I never had anyone teach me how to play guitar or sing, so I have to learn on my own :S
