I'm a Zelda freak if you couldn't tell...(look to the upper left of this comment :D)
I feel you should have pushed a bit further in expanding this song and pushed the envelope a bit more. It's hard to distinguish if this was taken out directly from a part of the game.
I would have gone a little further in re-creating the mood. Guitar solo? Naa j/k but I love that you chose this song to play.
