As a fellow composer...
...I can say I greatly appreciate the work you've done here.
Your piece is full, not leaving anything to be desired in its composition. Although if I had to guess, I speculate you're natively a guitar player or have at least given some effort into playing guitar, only because I haven't known many piano players who were concerned much with modal scales.
I can hear the John Williams influence in here as much of the thematic layer of this piece sounds as though it was inspired by Williams' "Hook" score which would only be appropriate for a piece dealing with the atmosphere of flying. When you mix the jazz elements in, the piece takes more of a Noriyuki Iwadare sound (the composer to the "Grandia" games).
The mix of the piece is flawless. While I place most of my focus on the composition of my pieces, I still have much to learn in the realm of mixing to perfect my mixes. But hey, music composition/mixing in general is an ever-growing and ever-learning process.
Congratulations for creating a wonderful work of art.
