Very impressive!
This is a very strong piece! At first I wasn't sure what to make of the slower bass beat, but once it pulls together around the 30 second and 2 minute mark, it makes more sense as a slow, determined piece as opposed to a rushed sense of action. All in all, very good stuff. If I have one criticism, your work could use a break from synth; try to inject some strings and wind into your work if at all possible.
