Ooo, this is really neat. I'm loving the direction you're taking this so far - that orchestra caught me off guard. It's dirty, it's interesting and it does have some Star Wolf in it, lol.
The thing that catches me the most off the top is how the lead gets lost behind all of the sound. I know the sidechaining is to give yourself some room, but that lead does need to come out ahead some of your other elements. I hear a lot of dubby sounds that just overwhelm the lead, when the lead should be the thing grounding the listener to the source (such as at 2:07). Having the sidechaining affect it a bit less and mixing the other elements a little behind the lead when it's present would help considerably.
Very neat approach, I'll be listening to where you take this.
