1. I think the kick needs to be a bit more low pitched, to get that lowend effect, sounds too midrange to me.
2. That synth doesn't sound bad at all to me man, kinda fills up the track, gives it some soul.
3. Im liking that evil synth in the end..........I think you shouldn't spread (stereo wise) that synth so much, maybe keep it a bit more in the middle, so it doesnt flood the mix.
cool track though :)
