It's been done before, and it will be done again, but here is my take on Tony Stark.
Entire figure is the Movie Masters Harvey Dent from The Dark Knight, just repainted. I know alot of people do a head swap, but the Movie Stark head is too small, and I didn't want to do the retro head.
I painted the suit black and gave him a white collar, blue shirt, and red tie. Hair is painted with glossy black to give it the sheen a genius, billionaire, playboy philanthropist would have. Lastly, the hardest part was painting the facial hair, but I think it came out pretty great.
