Noticed that you mentioned this was complextro, so I decided to check it out :p
Nice, soothing intro. I like the synths you've used in here.
Damn, 1:30 was powerful. I really like the high arp in the background, it really added a lot to the 'wow' factor, so nice touch. I really like the build-up as well, especially the pitch drop near the end.
I recognize a few of the loops in the drop which you've chopped up, and you've done a good job combining them. Unfortunately, the problem with loops is that they are usually already processed and all that jazz, which makes it difficult to mix them well.
Actually, perhaps it is your kick that is being a bit problematic in the mix. I feel like it might be taking up too much low end. Instead of bumping up the lows on the kick, perhaps you could add a sub so that the presence of bass is still there, but without the muddiness the kick is currently producing.
Try messing around with sub basses and whatnot, perhaps you'll find what you're looking for :)
In any case, I thoroughly enjoyed this from start to finish, so you deserve props for that. The mix may be problematic but the structure and synthwork is definitely spot-on. Keep it up!
