Ok, this is a beautiful piece you got here. Love the sound of those strings mixed with the south american style floute. I think it's a mix beetween Medieval, and indian's dance fire style. Love it!! Voice tracks were recorder by you? i think you should reinforce the "voodo dance" part with more voices. That would give it so much power. I'm talking about the 1:42 minute and forward.
PS: Sorry for my english, i know, it sucks.
