It has been served. Good job! I can definitely feel the Zimmer in here as well as your bit of extra awesome and kickass. It also feels... "Inception-y" which is a totally good thing in my book. This song is truly epic.
It certainly sounds like something he'd write, with the more prominent percussion, tense string section, and electronic inserts. Great work!
I guess that judging by the title "Trenches" this was supposed to be more of something that took place during a war. In terms of war, this also worked to give me a feeling of adventure and ambition. I'm not that familiar with Hans Zimmer music, but it definitley sounds like he has a lot of great stuff. It paced itself pretty well for four minutes and I like the overall theme. I am glad that I am becoming more familiar with your work and can give you the praise you deserve. You seem to have the same theme of ambition and courage.
I can see this being used in a game like Final Fantasy, Chrono Cross, or some epic movie. Definitely deserves its 10/10
