Not real familiar with this character. I believe she was a member of the Hellfire Club before joining the X-treme X-men. Not my best work. Was having problems with the belt and realistic shiny leather still eludes me.
I thought you were going for a matt rubber look at first. But I think you got your leather effect in those 2 lines down her back. The 'x' thing looks plasticy - if that's the look your going for then great.
