(Before anything, take in mind i don't know a lot of music theory so my vocabulary isn't the most appropiate).
Well, your theme does have the feeling of "exotic place", a bit of a jungle, a bit of a desert, but i see it more specifically as one of these desertic/faraway towns, the ones with load of textiles and earthenware and spicy spices and loveable people full of quirks. I doubt you'd find such a place in real life useless you travel some centuries into the past. The music seems to be too "lively", "full of energy" for a desert, which would be more desolate.
I was trying to remember some desert themes and the first i though this. Overworld theme for a planet that's somehow half arid landmass and half ocean.
