Very cool. Funny, I've been getting back into RPGs (like D&D, etc.), and this is like the stuff I'd have playing in the background. It fits an epic fantasy world of dragons, barbarian kings, etc.
Not sure if I hear (in the tymp.) the "sample re-triggering" that comes with rapid notes. Fortunately, it's very subtle. Overall, I particularly like how you weave together the contrasting notes (slow, med, rapid) across instruments. Really drives the motion forward. HNY.
