As a whole, the track was very nice. There were some great powerful melodies in the track. My suggestion for you is to make the drums crisper. They sound flattened right now. Also, the bass could be a bit sharper at times.
I really liked what you did at 2:50. The strings were great. However, you stop them early, and then repeat the loop 2 or 3 times. Instead, you could have fleshed out a longer melody with the strings.
Well, there is my criticism. Hope it helps. Don't get me wrong, I really enjoyed the song. In fact, that's the reason I'm suggesting all these changes.
