wow, I definetly do like the track. the subtle, sounding melody in the beginning is very blunt and nice. the brass bits add a nice sounding mix to the track, while timpanis add a more serious punch. I'm definetly digging this. the louder bass sounds around 1:10 are sick too, and you even incorporated more badass sounding timpani riffs. the buildup is perfect as well, and it loops nicely.
everything sounds authentic and clean man. sweet.
the only problem(not really a problem actually) is that right now its just a underground dungeon...there's nothing very arabian about it :)...you could use some arabian sounding riffs, by using harmonic minor scales or the latter. or maybe even a tabla or sitar bit would be quite nice. maybe a lead sitar could layer the beginning melody that you used in the intro, since it blends in once the louder brass and timpani hits, making it not so distinct. adding crash cymbals would also make this track have a more "epic" feel.
damn nice man, damn nice!
