I like the choice of using harp as a solo instrument among the textural bed of the strings and choir. It almost gives me older Final Fantasy vibes with the soundfonts. I think more countermelodies in terms of independent melodic and harmonic lines (even just changing up the rhythm a bit) could improve the orchestration of your track. Also, less quantizing on the strings, especially with that cello/string bass, could add more emotion and more of a smoother feel to the chord movements. Good job!
