I think you started with good quality videos and they have improved with each iteration.
The phasing in and out of scenes, that you did in the beginning, were not my preference, but you have since quit those.
I like the talking you do, the detail of your movements, and the angle that you use. I find them very informative, beside very enjoyable to watch. Music might be nice as long as they didn't overwrite your narration. You could do sped up motion, but usually there are good details in all your movements, that I learn from.
Your kind, gentle personality also makes the videos very enjoyable.
I do miss the red umbrella.
You are evolving and they are all good! Just don't quit ....... please. :-D
