The work you did with the lighting is a vast improvement. I've only recently come back to the forum, and I've seen a lot of your posts--the progress you've been making with these self portraits is fantastic. The second image in your second set is my favorite--your expression is vulnerable but your body language guarded (and I think the lighting is fantastic).
[I'm not sure if you'd be interested, but seeing as how you're working as your own model, maybe you'd like to look into the work of Cindy Sherman. There is a lot you can do with self portraits.]
I'm looking forward to seeing what you come up with
