Perhaps this would be better if i understood the words, but unless this is that kind of punk that doesn't care about sounding good, than you might need to try again. I think that you have something to start with, because you can play alright, and your voice isn't bad, but over all the sound sucks. A lot of that is in the recording, so if i were you I'd multi track your guitar and vocals out so you can get better levels and maybe put an EQ or some kind effects on top to fill it out a little more. I know this is just a demo, probably so you can have your friends check it out or whatever, so I'm probably being a little harsh... Also i don't know what your saying and that doesn't really help. So i guess... Keep at it you're on the right track.
