I thought that was great, I listened to version 2. Some nifty changes in there, unexpectedstuff. It sounds like it has a lot to say.
Which might be something to think about, because after listening to it, I couldn't recall a theme, a melody. It's a really really cool meander! Do you maybe want to develop a particular melodic line and feature that, and hang everything else off of it? Did I miss it completely?
The instruments you have chosen go together very well. Super movie montage music!
