I like it a lot, it's so well composed and orchestrated! I think overall this is a really solid, nice sounding track. The only thing I can say is maybe you can play around with more variation in your instrumentation in the various sections you have. For example, you have nice instrumental differences between the A and B sections, but the instrumentation stays very consistent within those sections, with the choir always singing the main theme in the A section, and the brass playing the main theme in the B section. Maybe passing the main theme to other instruments within those sections might help make your music even more exciting?
