No worries, I'm glad you like them
Great job! That looks great. Just a tip though, as you may know, the order of the images goes:
Top image = Normal orb
Middle image = Mouseover orb
Bottom image = Pressed orb
The main emphasis usually goes on the mouseover orb
So, in my opinion, the outer glow would be best on the middle image. But that's just me being picky! Really good job with those.
Edit: None of the above applies, you've changed the image since I started typing this
