Iron Man Space Marine

So I was sitting around before work and decided to work on my Carcharodons for Warhammer 40k. I have been working on and off with them for some time and just need to take the time to finish them up. Also I figured if I started posting them it would give me the motivation to do just that. We will see. The first I wana share is my Space Marine Assault Sergent in a classic Iron Man pose. Let me know what you guys think.
