What a great topic to discuss! Thank you for your advice. I am going to try out this smiling-to-serious principle next time...and I am pretty sure I will work perfectly! P.S. The audio of your recent videos is low. I needed headphones.
I'm not sure of the fishbowl comment. In those days, I was recording on my iPhone. The video looks like I recorded while it was still dark so the lighting on my face s*cks. If you watch newer content of ours, it will be much better.
