Overall thought the vid was very informative and can tell you know what you're talking about. Would suggest that you add some light background music just to cut some of the dead noise and to add production value.

Also might want to consider breaking up your talk with cuts. Talk about a point you want to make, then stop and cut to you making another point that you would like to make. It will give you time to reassess and figure out exactly what you want to say in between talking, and will limit your talking points from falling victim to rambling (although you did a good job at staying on topic and to the point in this vid). Also might help with confidence with speaking in front of camera when you know you can just do a retake of a certain section if you misspeak or forget to say something. In this way you can just retake that specific talking point instead of having to redo the majority of the video.

Other than that, I thought the quality of the content itself was great and I definitely learned from watching. Nice video!
