Definatly an Epic style
When listening to this, it does sound like a very dark style RPG. From this, it's very almost ominous... Well, I'm not sure about that. I love it. I am always a fan of different pitch percussion as the main focus (tom-toms and the like) and it fits perfectly.
If you do not finish your RPG (which I believe you probably will) I will steal this. Mwahahahahaaa! (jokes).
But All in all, I'd give a 9 out of 10. It fits beautifully, but it's only one or two single notes that just hit me as being off. It's hard to find and explain them, but one or two feel just slightly incorrect.
Oh and a 5 out of 5
