this is really nice. i think the way the brass enters at 1:00 is a little over the top and needlessly "epic" personally, i'd like there to be a more gradual shift into the full inception BWAAHs. otherwise, the orchestration is fantastic. strong main melody and good use of the entire ensemble, there's a real sense of journey and wonder in this. there's a brass note that gets cut off suddenly at 1:24, don't know if that's just a rendering error or if you misplaced something, but it would be worth fixing up if this is something you're using professionally. the reverb tail on the flute is cut off at the end of the render as well. phenomenal work, otherwise!
