Hi, Thank you so much for the video. It seems that You know a lot, and I want to learn as well. I have some suggestions for your next video. 1. Would you put some caption or subtitle on it. No offence, but you have some accent and english is not my first languge. So, it would be really helpful even for accesibility point of view. 2. You can delete your face. Most of people who come here are to get quick info. The circle with your face kind of interept views. Thank you for all the effort and contents.
