I think this is a cool look for Ultron. I made it a few times before, going full silver. Simple enough and looked great, but I always wanted to do something a little different with it. Add some gold and a cape, and go for a design inspired by the Phalanx Ultron. Which I thought was a good mix. I liked that event.

Head was from Ultron, dremeled to fit. Cape was fully sculpted. From there, a full repaint, and all done!
