I edited this post so that the video is now normalized.
I had previously posted a version of this in the Animation forum. Some people (not in the forum) said the video had low sound volume. After consideration, I’m thinking the sound is a Youtube issue. So I plan to upload the new version (with stereo voice sound) directly from my desktop, with no Youtube link. Then I will provide the link to this to the same people who had the low sound issue.
