Pretty good :)
The effects in the beginning are great and well-placed; especially that laugh. Oo, so sinister. Can't get enough of that :)
When the main song comes in, the synths don't really have as much impact as I feel they should. I should be able to feel that sub bass/reese like none other. It really just sounds like a detuned saw. Come on, brother! Distortion, flanger, phaser, anything you can think of; modulate that fucker. Make him sound pretty :D
The drums sound great, but one word of advice: less bass drum. Make the patterns sound clean and organized.
Keep it easy;
