Powerful
Nice opening chords. Though I have to agree with Gravey, the arpeggiating strings could probably use some work. Not only does it seem to be highlighting some odd notes, but I think in general it's just a little too loud. Given how their range is generally much higher than everything else playing at the time, it could probably stand to be a little quieter.
Though in saying that, the ones that come in at 0:44 work very well. VERY well. At 1:25 now and I the one fault I can find is with the arpeggiating strings. The piano and brass entries are very nice, very powerful. Especially at the 1:50 mark, where everything kind of culminates.
The build-up is nice and structured, in general it's got a lot of promise. Even if this is a WIP, it almost works as a loop by itself.
It's got the promise of a beautifully majestic air, I'd be really interested to see how this sounds once you're done with it. Nice effort, overall. 7/10, 4/5.
