Can you please crit my singing?

Hey, I'm wonder if I have the ability to sing in a band, our band would mostly play Acoustic or alternative rock, here are some examples, http://soundcloud.com/JosephJamesJOhnson
I've been singing for roughly a year, and haven't practiced for a while so These are not my best. Thanks so much for every comment!

I think you have a good voice, a very pleasant tone to listen to. It's overpowered by the guitar somewhat, though, so it's hard to judge more than that. Good work!

Quite nice, nothing that a little volume wouldn't fix.... but that will come with practice
