I think it's Morgan Fairchild instead.
There's a manga look to it, too.
Ha! I think this last issue pretty much settles it. Moonstone and Carol fight over a theatre playing the movie Who Dat Ninja II starring Tracy Jordan.
Pat just reminded me that this movie is a running gag on 30 Rock. Tracy Jordan is Tracy Morgan's character in the series. Obviously the artist is a big fan of the show, so it's not a big stretch to conclude that he did indeed model Moonstone of Jane Krakowski from it.
