Maybe one way to encourage more comments is to ask your viewers a specific question at the end of your video, like what Ray William Johnson does, and tell your viewers to put their answer in the comments section.
What question you ask is up to you.
Perhaps that will make the viewers less shy about leaving comments and hopefully encourage interaction and feedback on the video itself.
