The progression in here, especially when the choirs kick in in full force, is sublime.
It also does sound a tiny little bit like A Fleeting Dream (from Final Fantasy X), albeit if you did a much more sombre iteration using a leitmotif from there.
Work on giving your track more air in general and increase that reverb tail in the end; it does feel a little bit stifled. Otherwise, your instrumentation is solid, your vocal harmonies are on point.
