Just one thing to be careful of, and that's making the stars TOO bright. I see you pumped them up quite a bit on these latest shots, and while I agree it's nice to see the stars, in a few shots they look too bright...
As I'm sure you know, in reality we would never see stars in ANY of these shots, since the camera's apeture would be stopped down to expose for everything else in frame. Of course, this isn't reality and we want to see stars, but personally I've always opted for just enough brightness so you can see them but no more.
