Constructive critisizm wanted...

Hey guys

I am a 19yr old bedroom dj and producer from scarborough. I have been producing for just over a year, so my tracks are still pretty shite, imo. Despite my tracks needing lots of work, I launched a myspace a few days ago so people can hear where I'm at with my producing. I am looking for a bit of critique from other producers on this site! I'd very much love to hear what some of you guys think about my tracks, and feel free to post any constructive critisizm...thanks
