I like the drama and climactic nature of this piece. I must say, however- a lot of those instruments don't sound very authentic, which I think you touched upon in the description. However, I like the structure, as well as the melodies and percussion. The ending was good, too. You also might want to transpose that violin part at 1:03 down an octave. It seemed a little too penetrating at its current pitch. Still, overall, good work. I appreciate how engaging and dramatic this piece is. ;)
