Oh man!! It sounds so dark and evil especially from 0:30 to 0:52! It's a really good piece in my opinion. It sound epic throughout the middle due to the epic percussion and the bass runs in the background. You're really good in making 'evil' music. It is so refreshing to here such music, if the only epic music you here comes from hollywood (especially Hans Zimmer and his gang, although I like Hans Zimmer).
Keep up your work!
