For me the thing I enjoy is that you are setting realistic expectations, not being wasteful (I notice you start from the edge of the paper instead of cutting from the middle, etc.)
yeah, I heard this from others as well but not something I particularly aim for at the moment (I could easily release a second version of a video with the original sound though). Although sound/music is one of the bigger questions/challenges I need to 'solve': it's quite difficult to strike a balance between setting the mood for a video and too intrusive. Pure original sound is difficult for other reasons, mic quality, background noise etc.
I would watch that even as a grown-up.
