Hey Dave, congratulation on your 1st video at your new lab.
Well, brief impressions, looks alot better than the old one, also I love the background better than old one, maybe it has the white wall behind those equipments that giving me a better spacious feel rather than those old bricks wall.
Although I'm not the expert on lighting stuffs, at the new video, maybe you could add some light at the right hand side to lighten up a bit your left face, and its better than the old one where the light came from above your head.
Btw, the sound is also better, not sure why, maybe its in bigger room.
Here an example to give you the idea on the ambient light comparisons on old vs new :
Again, thanks for the latest video !
