I don't know dude, I mean you did transpose this well but this is litterally Gerudo's Valley. Like you didn't really remix it, it's just the song. If I went and got on youtube and looked up the track from Ocarina of Time I would basically get the same thing but a little bit better.
A remix should really something new where you take a new spin on it in some way. I almost thought you stole a midi version of the song and just put it up there.
I hate using myself as an example because I suck a lot, but if you listen to my final fantasy remix it is the same notes (like yours), but I did it in a weird dance/violin type thing. It obviously wasn't the original, it was a remix in some form. I even added a 2nd melody to it for like a verse so it had something totally of my own.
Sorry dude, it's always fun getting to put together one of your favorite songs, but this litterally is the song.
It's not like terrible though, you did pick decent (although super fake, faker than the original) instruments, and its not badly mixed. Most of the parts come out pretty clean.
But keep making music dude!
