I like the instruments and the pacing. It starts off slowly, but gradually picks up. The bass and kick add a lot to the piece as it is, and I'd say you have a solid intro during the first :45 seconds or so, but after that it was rather repetitive. I think you need more harmonies and counter melodies to create a fuller, more engaging texture for this piece. One method you could use to increase the intensity would be to hold out the chords for the entire measure. This is a good start, but as I see it it's kind of just the skeleton of a piece. Please keep working at it, though, because it has potential. Hope this review helped. ;)
