Hey Jay, listened to this a couple of times today.

It's really well put together, but for me it doesn't develop enough.

That synth line builds up to getting super fat and then the kick comes in at 3 mins, then it drops away, only to rebuild to the same at around 5 mins.
As others have mentioned, that drone sounds real nice, but it needs to do something else.
When I first heard it, I was expecting it to shift in pitch, get chopped up around the beats and really get messed about with.

Also, with the bouncing panning noises you've got at the start;
I was expecting them to resurface, and somehow get wrapped around that big noise you've got going on.
And it is a big noise, it would be a shame to waste it :)
