Lovely soundtrack! I really like how expressive you made each track; I really liked the Chamber of Secrets. And the final track To Fly Someday was an excellent solo piano track that tugs at the heartstrings.
Just a slight nitpick; some of the tracks had some noises that I don't think were intentional; Aria of the Sky had some clicking/clipping noise at one moment and To Fly Someday had almost a low microphone feedback hum near the end. The tracks are wonderful, but these small things took me out for a moment.
Otherwise, excellent work!
