That Captain Atom... Makes a great empty palate for anybody Ed McGuiness ever drew!
This one was a step up from the Hal Jordan I did. I shaved off the hair and nose and sculpted the head. Kept the eyes visible. Then, just painted it red. The tricky stuff was the sculpting, for which I used Aves Epoxy Sculpt. I'm still not sue it's strictly better than sculpey but it definitely cures easier.
Then, just slapped the black on 'I'm with the white highlights and called it a day!
