OK
The start, plain and boring, needs something else. The snare at the start for the build-up needs to be fixed, but the one in the middle of the song is good as it gives it a scratchy style :P.
The melody in the middle should change, kinda like the scratch, but something different. It feels a little lifeless but that could be changed with something (dunno what) and it just ends abrubtly, which of course you will fix, but around there you should come in with a silence or something and maybe try some piano work or something with a little build up.
Well thats all for now. Come check out my stuff and tell me what you think.
