hey, I just wanted to give you a quick few thoughts here: 1) If you are creating cover arrangements, by definition you are not making the musical composition. However, in your videos, you correctly identify the original composer so I think this is just a language term
2) I agree that what you want to say is that you are orchestrating the arrangements, using your own sound files, libraries, etc., I think this is valuable, but the challenge is YT can't easily see that. I'm trying to figure out how orchestators can best "show their work"
