Marvel Studios conceptual illustrator Andy Park has uploaded some more of his concept art for Josh Whedon's Avengers: Age of Ultron. Park uploaded the pictures onto his Facebook page saying
""And here are a couple more initial passes at the Ultron design done for Avengers: Age of Ultron as well as the approved design for Ultron Mark 1. I don't get to do the more robotic designs that often here given our resident robot experts in Ryan Meinerding, Phil Saunders, along with Josh Nizzi and Josh Herman. But when I do get a chance I just savor the moment. Too much fun!"
