Kewl.
In short, the beginning part was awesome but the rest of the song doesn't quite live up to it. I love those chords in the pad you used, and combining it with that clap and hihat sounds great. I don't quite get the shift/control thing, but it sounds cool haha.
Once it quieted down, I kept waiting for it to come out into a big hit with maybe a tempo increase. It did change, but it took too long. The last part needs a little work I think, you did imply that this was a work in progress so I think you should add a lead synth in there carrying a melody. And instead of having it build for a couple bars then go back down a few times, the whole thing should be building the whole time up until where the song ends now. And then for that ending you're talking about... I don't know haha just make it sound cool, you clearly have the skill.
So I probably over-did that. But I'm really hearing a lot of cool stuff in this, and I'd like to hear it when you've put that ending on it. Shoot me a PM when you finish it :D
