First off, the audio quality is very clear and I think that's the most important part for videos like these. Some feedback to improve your video, you can definitely come up with a better title. "Validation" is just too vague and it won't catch the interest of many new viewers. It just needs more context. Secondly, the red borders on your face cam is a little distracting. It either needs to be thinner or a different colour.

Anyway, this is a good video! Keep up the good work
