That's pretty dark and evil sounding Lau. I like it thus far. Maybe add sample a scream from an old horror flick and put some fx on it. Then you can use it as a pad and pan it around thru the mix a bit. Maybe even sample the sound of some electricity for in the break just before the beat comes back in. Kind of like a machine powering back up.

Ha Ha, the track just gave me a cool little mental picture.
