X-Men
That is a very nice icon.
There was a cool FRUA design by Nol Drek about the Dark Phoenix Saga. I think it would be fun to do a Marvel design.
I don't have an icon for Juggernaut yet, but I do have a model to work with.
Here's some icons I did a while ago (not quite the way I'd do them now, or as high of quality as I'd like). Some of these are using images from video games.
