I can't say I know if she's a good guy or bad guy anymore, but Emma Frost is still pretty cool. Cold, even. Her costume is pretty impractical, but when I was reading X-Men, she wasn't much of a combatant, either. Artwise, I tried a lot of different coloring techniques and textures by coloring it in Corel Painter. It's a little more painterly than some of the other pieces I've done, but I think it suits her.
I have to say, I also really dig the expression and her right hand, both of which took a lot of redrawing to get just right.
