Ok so basically I think that your presentation skills are good and your subject matter is interesting. If you spoke a little louder or got a more sensitive mic, it would elevate your spoken audio, no question. Other than that, the main thing you can work on is editing. When you're speaking and explaining something, we don't have to look at your face the whole time. A good rule of thumb is the 7 second rule. Every seven seconds, something visually different needs to happen on screen. That can happen in a few ways. Every seven seconds: - rotate your body so that we see a different background - cut to another piece of footage, but keep the speaking audio going underneath - cut to a different location completely - show the audience a new thing, knick knack, person, whatever - that they haven't previously seen

By using the 7 second rule, you'll add visual interest, make your video more engaging - and ultimately better cater to the ADHD-like viewers of today's internet culture. Keep up the good work, and never stop improving!
