This is absolutely beautiful. With most cinematic composers on NG, I've noticed that I've never heard a track that doesn't have some sort of climax. I think the fact that this doesn't actually build up to anything but really just remains consistently beautiful goes to show that you don't need this 'huge' sound to create something absolutely beautiful.
Seriously, I could see this for some reason in an older Tomb Raider game (if the quality was lower that is!) So beautiful. You've earned yourself a new fan :-)
