I really was not expecting such a fast beat on top of a hard sounding intro! I think this one you could take an approach of a fast hook like you had here, and a slow, typical hard style hip hop breakdown in between, using some different distorted samples. Could be a nice way to extend this beat.

At the end, the delay is a little bit unanticipated and makes it sound unfinished, but I definitely like the olskool sounding sub you got going on. Nice work!
