It's really heavy, which is a good thing, but the different elements aren't very clear within it: I can't hear them all and they all get lost in each other. I can't actually really judge your sound design at all because there are too many things going on and covering each other: 1.35 almost comes as a relief because you can actually hear stuff.
The volume keeps varying in the second section and it sounds weird. I don't support you know why?
You either need to get rid of some things in some sections or do some serious mixing to separate them out.
