Mix sounds alright to me, although the vibes or marimba or whatever only in the right ear bugged me, since that's the most constantly going thing and there's nothing to balance it out in the left ear, it was kinda nagging. I felt unbalanced listening to it :p I'd say try centering it or panning it back and forth from right to left.
As for the song itself, it's a great rendition of Goron theme, more of a OoT feel than TP- although the two are almost the same, TP's has a slightly less cheery, Caribbean feel. I'm pretty sure the first note in the vibes melody there is lowered a half step or two, which changes the way it feels a whole bunch.
I bring that up because there's a big difference in tones that the different games' music conveys. With the more major melody, OoT has a much brighter tone when you're in Goron village. It feels like a party. TP feels much more foreboding and less friendly, and we should consider what kind of tone we want to convey in our game. You've got a great mix of the song, but it is a bright, cheerful mix. It might be worth looking into a way to alter it a bit to seem more desperate, standoffish, etc., to emphasize the tone of the Goron section.
