Have to say that I really liked this piece. Video Game music is a really interesting genre and this song is a good indicator of why that is. When I was listening I couldn't help but think that it reminded me of some of the music from Mass Effect 3. It has that kind of quality to it. I feel like it belongs in an epic battleground scene.
I can't really make any suggestions for improvement because the song is already so awesome as it is. It's just a really fantastic song.
Thanks for scouting me, by the way.
