This track really is very beatuiful. I am very honored to have been part of this track by way of inspiration. You are a talented musician and composer, especially for your age. Not saying that this wouldn't be considered good if you were older, but that since you're already this great at only 17, surely you'll grow up to become extremely good at composing.
This is already way beyond my level (at least in orchestral music), especially when it comes to dynamics and mixing.
You have a brilliant grasp on melody and harmony. And I sense that you can also feel the music, instinctively, which is very important. For example, I think that the name and theme are very apt, and suit the atmosphere.
There is some volume dynamic going on as well, if one cares to listen to it. This track didn't even need any percussion. I guess you could've tried adding some atmospherical cymbals or deep toms somewhere, but I think that this works just as well without them.
If I would have to give any criticism at all, it's that I feel the final notes could've dragged on for just a little longer. The ending could've also been structured in a way that it was hinted at, for say, the last 15 seconds or so. But upon relistening, it sounds just fine :)
Also, I like that you ended the piece with a chord that sounded a bit inconclusive!
All in all, splendid job. It's great that you finally got to finishing up the album :D
I myself am thinking about eventually gathering the best of my piano tracks, and creating an album out of them XD
