I saw both of your videos, good shit dude. Little too long, but that's okay! You're still learning, that's the point, you're learning AND helping others. Not many people willfully do that.

Suggestions: If you want to edit videos as a professional, use DaVinci Resolve or Adobe Premier Pro.

Video topic suggestions: Explain the merit system too if you're making the other videos you previously suggested. Also, I am sure a lot of people would love to collab with you on this, so more the merrier.
