If you really want to build viewers to your channel - you're going to need to play it live and record it. No one really cares about a bunch of scrolling notes...Believe me, as someone who does the same thing you are doing (arranging music).
I’m a fan Koji Kondo and I’ll give credit where it’s due. But do you think anyone would say my double fugue in the development section is an arrangement?
Yes, it contains paraphrases and material used by Koji Kondo... it's still an arrangement. You've taken his material and although added in your own as well, is still an arrangement. If you took out everything that WAS Koji Kondo's music and left it, you wouldn't have much left.
I do know one thing, he may have made the tunes but I made it a masterpiece.
That statement alone completely outlines either how arrogant you are... or pompous. You didn't make this a masterpiece, Koji Kondo WROTE a masterpiece... I've got no problem if you have your own compositions, but don't make statements like the one above - that shows a level of dillusion, not commonly found in sane people. However, on a nicer note - some of your original compositions are well written and sound quite lovely...
