UPDATE: December 29, 2013
Whew! Right panel complete. That big silver area always makes me go cross-eyed! 
After I did the silver, I went back and finished detailing the gray chips.
Then I added the gray and silver to the other areas on the right panel. I finished by
adding the really fine scratches with my compass point.

I'm saving the contrasting pale gray color until the rest of the helmet is painted.
There's not that much of it and it's easier to do it all in one session.
Next up will be to lay down the base color on the dome and inner cheeks!
