Pretty epic! I imagined the evil boss rising out of some evil miasma at the beginning. I really like this.
I think some of it could really be filled out with more audio, just so it maintains an urgent sense. Otherwise I really think you nailed the "evil" feeling of the track. For example, the parts like 1:42-1:44 could last the whole thing and make it intensely more dramatic if desired.
Well done regardless.
Superb! This would be a majestic theme for a boss. I could really see it in a castlevania fan game. Kudos to you!
