Hi Dave, since you asked for feedback, I have two things to say:
I don't mind your screen not filling your background. Maybe try an asymmetrical layout though, i.e. move the screen over to the right side of the frame (from the viewer's point of view). That will then allow you to just scoot over slightly to the left on your chair to discuss the lab shown on it, rather than the awkward standing pose you've employed today. And frankly, the gaming cabinet might be nerdy, but it's way less interesting than the stuff that might be sitting on your shelf.
Second thing, you're probably aware of it, the lighting is still way off. Your captioning says your squinting, i.e. it's too bright from where you're sitting, but it's too dark from my PoV. I'm sure you'll have it figured out soon enough, lighting has always been something you've done so well.
Aside from that, I have one wish: replace those puke green mats with some new blue or gray ones. I know they were different when you bought them, I watched all of that. But they frankly look disgusting now. Replace them. Do it now.
Btw, do they still have the same electrical properties as they did when they were new?
