A very beautiful and serious piece!
The piece flows naturally and has a great buildup. For me it feels very "film musicesque" and this fits that genre very well.
Regarding how I rate the challenge itself I find it a bit lacking. On one side I feel like the genre this piece operates in can be hard to be creative in but by no means possible. And, many pieces operating in this genre don't need to be creative to be insanely good. But for me, I wish there were a bit more variation, maybe not in the material presented but in the how. I also felt that while the piece had a good buildup it could have a better outro, as of now it feels like it kinda ends. Again these things vary depending on which genre the piece operates in.
Has a great mood with a good progression and seems very fitting for film music!
