Great work!
I thought the voices and strings worked very well, and the percussion panning was done very professionally as well. Some interesting rhythmic and melodic elements in here giving this piece an eerie, dark feel to it. I thought the piece could have either been shorter, or included more variety (modulation, tempo change, stylistic change, etc) somewhere in the middle to give this more form. Also, I'm not really hearing this as a classical piece of music either, but that's just my opinion. I thought the piece was mastered beautifully as well, nice job!
