Mr. Atom Triumphant! (Or, When Mr. Atom Meet Ultron and Brainiac)

As I've mentioned before, one of the problems with rearranging your galleries is when things go "missing". My apologies to David for his cool piece going MIA for so long :\

David'd had a sale on commissions and as I'd enjoyed his work Northern Guard too I asked him to do a coupla ideas that I've had rattling 'round in my head for a while. The second was a god ol' fashioned match up between Marvel's Ultron, along with DC's Brainiac and the old Captain Marvel / Fawcett robot Mr. Atom. Such a great piece from David. Can you tell that David was able to pick up on who my favorite is?
