This is awesome, you nailed this style. Honestly this made me want to play Mass Effect. I can't give you any technical feedback because I'm no audio designer, but from a pure listener standpoint I was moved. It was moving =D
What I'd like to see next from you is something in the same vein but with a little more touch of your own style and individuality. While this was amazing, you are right it does feel very Hans Zimmerman.
I never thought of the Mass Effect side of it, but I can see what you're talking about. It always makes a musician ecstatic to know that their music touched someone, so thank you for that!
I was planning on playing around with this some more, this song was at least made in part to play with my new sounds. But there will definitely be more like this (well, not exactly like this...I like the chromatic palette, personally), and I'm so glad you enjoyed this so much! :D
