I was going to write that it was good that you didn’t say “um” all the time. (Being silent in pauses is in my experience a learned skill for most people and one that comes once one has heard oneself say “um” too many times.)
The sound was fine. I think your (Jabra?) headset did its job unless that was also the result of editing.
The imagery got a bit distracting because you look to the side of the camera. No problem for podcasts, but for video it’s better to look straight at the camera to look at the audience so to speak. (Also a learnt skill.) So maybe a webcam you can place in front of the screen you are presumably reading of?
No idea about marketing a YouTube, but you got in the “like and subscribe”, so that is probably good.
From topic and lack of citation I just assumed that they had an LLM write it.
