The harmony vocals sound a little strange in the chorus. I'd say fill out the harmony better or nail the one you have a little harder. It's almost like you're missing the lead melody and it's all harmony.
I tried to go back for a second listen to make sure I agree with myself...but the link keeps locking up the page for some reason??
Anyway...here's my two cents.
What I liked: the groove was fun, the guitar work was nice, mix of bass/guitars/drums is fine.
What I didn't like: (and please don't take this personally b/c I'm not trying to be mean)...the vocals were kinda "nerdy" for this song. While you can sing in tune and all, I think the layers of harmony gave this a "Carpenters doing a Bob Marley Cover" feel. I think you could sing this better b/c your voice and this song has a feel similar to this guy... http://dl.dropbox.com/u/13390899/07 Restless.m4a
