That intro makes me feel like I'm waking up and preparing to go on an epic adventure! It actually kind of reminds me of doing just that in The Legend of Zelda: Ocarina of Time, as well as a handful of other classic video game orchestrations. Some of the early chords around :21 do seem to possess a bit of clashing dissonance where the deepest strings are concerned, so that might be worth looking into if it was not intended. I really like the progression of this track from start to finish, and some of those chords take unexpected turns that really draw my attention.
I think the biggest problem is one that I suffer from, as well: sample quality. Not everyone has thousands of dollars to spend on things like high-end East/West orchestral suites and Omnisphere! Not that we don't wish we could, of course. Thankfully, the judges for the NGADM don't tend to let sample quality affect their overall scores and instead listen to the heart of the music. :)
The one instrument that really does stand out beautifully from the rest is the oboe that begins playing around 1:54; it sounds brilliant and has such presence. In fact, your build here is one of my favorites throughout the entire piece. You then release that built up tension with some lovely, slow piano arpeggios and a very nice choir that fades off into the distance. I found it to be a fairly simple yet effective ending, to be honest.
Ultimately, I found this to be a very soothing piece of music. Not much in the way of Cinematic orchestral entries thus far, so I found it to be a refreshing respite from the more hard-driven, thumping beats. For that you have my thanks, and I wish you the very best of luck in both the AUC and ADM!
