It wasn't changed much in my opinion
Well, i definately haven't heard a version of MK like this. It isn't a whole lot different from the original, and its short. You should have made it a little longer, cuz it is good. the ending is the best part. I think the original composer deserves the majority of your score for this song because you didn't change it much, but I'll give you an 8 cuz i love the song.
