Very nice painting
This was nice to see such a good picture of Iron Man made. At first I thought this might be a picture made from the creators of the Marvel Vs. Capcom 3 sneak previews. Let me just say that Iron Man looks a whole lot better when he comes off as being serious. This is just like the comic book or movie version of him. It seems to be taking place in a foggy area as that is what is in the background. I love how he manages to look so triumphant while only being on one knee.
It's a little hard to check out the specifics of his costume. The digital paint really works well to still include the details and colors of his costume. The shading is also great with the white streaks on the side of his body. It gives you a better impression of where he is at and what situation he is in. The fingers look a bit too cartoonish, though.
