Whoever photoshopped the ingame graphics to look like that is damn good. I'm particularly impressed by the middle one with the VD walking with Dogmeat but am amused by the fact that the VD is the worst looking thing there. I'm with Wooz on the third picture, the sky really makes it look bad. The first picture looks like a combination of touched up concept art with CG from the game and I don't think the two mesh very well in it.
Whenever I look at the Power Armor I'm disappointed the helmet reminds me of what it was and should be and pushes the big first domino in the line of what's wrong with it.
