Nice.
I'm noticing it gets a little boring after about 2 minutes or so. A little change would be good. The beat's nice, a little ghetto for a white boy like myself. It picks up and gets a little interesting after about another minute. It's a good ambient track. It could use a melody, but for ambient, apparently your specialty, it's pretty good. 9/10, 5/5. Above average work, mate.
