This effect is very creative, maybe there are even guitars with a screen? I don't know, you have done well with the song making changes in the tonality, it is a beautiful song and has a timeless message about the importance we should give to mother earth, I can't tell you if the use of the Disney video is the most appropriate in terms of copyright, but in a creative way it has been very beautiful because of the contrast between the grayscale video and this colorful guitar.

I agree with you when you say that Disney songs convey a beautiful feeling, they are so well thought out that they are great, thanks for sharing a story and a song.
