You've got some great instruments at play, and your harmonies are beautiful. Actually, I find your main theme extremely reminiscent of "Colors of the Wind", in Pocahontas.
The second segment of your song is perhaps the most creative, and the composition is very nice, and definitely fun-sounding. Upbeat for sure! In fact, if I was in the setting of that movie, I could definitely imagine a festival going on.
So, I like that you've divided up your track! Strays away from the conventional "song"-type ideal. However, this sectioning of your song left your transitioning at an awkward state. The transition to your second section was sudden, but fit better than the one to your third. A little more work on your transitions could help the slight disjointedness of the song.
I hear a couple key errors, one at 1:10 and with the strings at 3:15. I hear one at 1:45 with the bells, but that is very minor.
As for your ending, the strings cut off rather numbly, which is like a door shutting in your face compared to the beauty and grace earlier in the song! Perhaps add a bit of decay at the end, or aim for a stronger ending? It just didn't sit right.
Your volume is also very low, so when you make your newer version, you may want to considering increasing it! Although they sound alright, I find that your DSK instruments are not able to breathe properly as they are now.
Overall, this is a very nice cinematic-type piece that could use some work. I look forward to hearing your extended version!
