You made a Drum and bass song and put some Big Beat stuff in there, it's simple, and very effective, the single snare and percussion, one of my favorite matches.
One thing I thought was over cooked was the repetition in some of the patterns. And even though you had to make time, the cut off on the loops kind of threw off the hook that was there, but my favorite part is definitely the beginning. As you sneak into the better part of the song, you should take it easy on the ambience/build up. Too much can choke a song and the funk it has.
Otherwise, damn nice job.
