I absolutely LOVE Ironman! This is a piece that I created quite a few years back, and being in a bit of a throwback mood, (dang Star Wars Day has me all nostalgic) here it is . . .
I also produced an orthographic view (you can see that here at http://zdcoe.com/pages/art/ironman.html). Loving Victorian style and Steam Technology, I decided to mix them to create my Steampunk version of Iron Man. Lots of fun!
