Avengers: Infinity War (2017) - Hulkbuster Mk2 concept

A couple of Hulkbuster concepts for Avengers: Infinity War. I was pretty crammed when this came up so only had a couple of days to produce some sketches. I ended up submitting two of them as works in progress. Josh Nizzi nailed the final design, but I kind of liked one of my designs so I polished it up after the fact.
