The piece by itself sounds really cool, but as it was said before me, the ending is a little bit strange...
Anyway, cool tune!
Keep it up.
PS: I love the Drum at 1:00.
hehe, reminds me of partyboy a little ^^
But it's really good. I always complain that artists don't put enough background emphasis, but you worked it in nicely, never having less than two things going on. You included an awesome violent bass beat with an appropriate amount of distortion and by doing all of this, you managed to keep a steady theme and mood. The breaks you included at 1:40 and 2:20 for example gave just the right amount of pause to launch back into the music. I particualrly likes the thing at 2:48 and 3:00 where you played around with the theme a little. At 3:25 and onwards untill 3:40 there was some odd distortion which kind of pulled me out of the piece, IMO a bit too odd of an ending, but it's the core of the piece that counts I guess.
