Voodoo13: I assume it was an IW dude who took the path of nurgle millenia ago. He still wears the IW armor but all his mutations are nugleish.
It's funny how you painted the stomach area in flesh colors, makes him look like he wears nothing but a bra :)
Good paintjob but it's just not Iron Warriors. You could have shaved the shoulderpad down or covered over the nurgle bits on him at least.
7 for a good paint job, but not for the modeling itself as you didn't do anything to it.
