Airports..
I'm a really huge fan of big texturey walls of sound, but the beginning of this is just too much I think. Perhaps if it were faded in and out, and where just so suddenly intense. Although, I suppose that is a lot like an airport. I enjoyed when the drums started, but it would've been nice to have a change up in the bass at this point, I'm not really seeing the "blue or purple" sky you're describing. It's a good tune though. :)
