Away: This is a really epic build-up! I love the echo fade out at the end.
The Will of the Wind: The fluttery piano conveys the freedom of the wind to storm whichever way it wants. The classic + lo-fi blends quite well here. You describe an epic scene, but this piece feels so calm. I think that intense movie scenes like battles or storms accompanied by sweet melodies or calm ambiences are really special because instead of composing the action, the music instead works in conjunction with the visual image to portray the emotions that may not be apparent on screen - it would be super cool to hear this in conjunction with the images you are imagining. My favorite moments in this piece are the bass slides that add an emotional heaviness and also feels like a cresting wave.
Starfall: Those opening piano chords feel so magical. The synth arpeggios following feel very spacey and magical as well. The chord progressions feel very much like David Wise pieces from Donkey Kong Country in an epic adventure sort of way. This is my favorite track from your OST.
Final Horizon: The thing I think that is most notable about this track is the use of delay and how that makes me imagine the rising sun as you describe. It also gives a sense of reflection on the adventure like you are constantly being reminded of what has happened on the journey.
Goodbye to a New Home: These are some beautiful piano chords that have so many colors and convey a lot of emotion. The chord extensions grow as the song progresses to convey the bittersweet nature of finishing an adventure but also having to say goodbye to the good times. This was an extremely pleasant soundtrack to listen to. Great work and thank you so much for sharing!
