Oh, wow, this is a very pretty piece. It has a lot going on and carries a lot of emotion, which makes it an excellent cinematic piece indeed. No wonder you've been working commercially, haha.
Since the piece isn't authorized for commercial use, does that mean you'd like to keep this here as a sample of your work, but you'd prefer no one uses it in their animations on NG? :) Not that NG animations are usually commercial, but I'm curious.
In any case, this is the first song I've heard from you and it's lovely. I'll have to listen to some more!
