Sounds like a lot of cinematic pieces I've heard before, which is not necessarily a bad thing. Try experimenting with different chord structures. Other than that, you've made fantastic use of your synths, and they sound very nice together. I can't imagine how much time it must have taken to write.
Transitions are quite nice, though chord changes are very predictable in the main theme. Overall, however, the piece accomplishes what it sets out to do. Production wise, watch your high end. What sounds like a trumpet or horn rings in my ears a little bit on both of my speaker systems, as well as studio headphones. Otherwise, good work. Your use of timpani was what initially grabbed me. Nice!
Thanks for the request!
