Slick!
Quite interesting work you've got here mhb! I really like the oboe lead you've got going on here. Not often you hear the oboe leading a piece let alone for an Arabian theme.
The brass you used, and how you used it, along with those drums did not really say "Arabian" to me. But it did say Danger, which suits the Dungeon aspect very well.
Is this Edirol Orchestral you're using here? The song also loops incredibly well, though there was nothing less to expect from a game loop ;). Well done.
I would have liked to hear some high end flutes here, I feel they would have more emphasized the notion of "wind", which is a common element to have in an Arabian piece. Desert winds, you know the story.
All in all, work well done mhb! Keep up the good fight and keep em coming!
