What I love about this is the subtlety. To me, keeping things subtle is always sexier. Here, you have the beautiful Susan Storm with her back to you, giving a mysterious smile as she undresses from her tight suit. Is she undressing because she's teasing you, distracting the villain, or is it because her powers worked better that way in the 2005 movie? I can just imagine her completely vanishing, because it looks like she's just in the midst of the act due to her disappearing breast. I also like that you put the 4 logo on her shoulder to be clear on just who this character is.
