WWII era Iron Man concept

I wanted to come up with a Steampunk Iron Man - as if that's never been done - and I ended up with an Iron Man design from World War II. His escape story comes out of Nazy Germany, the Mark I being built from failed/scrapped Nazi fighter jets. I was going to be adding even more designs to the Mark I, like an "01" painted number from a tail fin or something to the thigh or some other big part, but this was just a quick sketch.
