Not bad. The sound design is a little generic, but I like the busy beat and harmonies. The part at :28 sounds like a completely different song, though. If you're going to put several different themes into one piece, it helps to make sure they're tonally related. Then you go back to the original theme at :55, but it's still not so clear to me how that related to the part at :28. The bass is really loud at 1:18. A good rule of thumb is that the loudest instrument in the mix should be the snare. It was also a bit bizarre when the bass got suddenly much quieter at 1:29. I liked the pulsing synths at 1:40, but the pause at 2:24 was so sudden I thought it was the end of the piece. I think you need to add some reverb or a crash or something to smooth over that transition. Stop-start transitions can come across as jarring sometimes if you're not careful. The loop is pretty smooth, although the last 4 notes at 2:36 aren't necessary IMO. Overall, not a bad track. The transitions and balance are the main things to work on, I think. And knowing how to make cool sweeps (as you clearly do) is a good start towards making smooth transitions. Keep it up, man. ;)
