At first I was having an issue keeping track of the beat, and I think the intro needs some work. When the beat drops though that is pretty awesome and I think what you have works pretty well. The song is way too short, but sweet.

I wasn't too big of a fan of the high-pitched synth at the start of the song but it sounded a lot nicer when it was moved to the background when the other instruments kicked in around 0:30. Kind of has a video game ring to it. This is a real short piece so its hard to say much, but I'd like to see it extended and have some added movements to it. Right now it just cuts off real abrupt and doesn't feel like its made its mark yet, and it definitely has potential to make a big mark

DAT INTRO SYNTH. SO CATCHY. Curious what VST/soundfont you got it from? Also I love this overall, here's my criticism:

1) Maybe don't ever fade the intro synth out entirely. I think it would do a really good job backing the dubby part, fade it a lower volume, and keep it running as a hint?

2) Whole track could be louder! The kick is great, very clear and cuts through the other sounds, but it's a little louder than any other instrument. The dubby-saw-thing, background synth, hats, snare could be a little louder!

3) Dat ending! So abrupt!

4) Too short! Argh I want moaaaaar lolololol

Good stuff ;D

DUBSTEP!!
