Nice pic. I like the P on her hat and the star shaped chain. Though that second wire coming from the Wiimote confuses and irks me. That aside this is a very nice Power Girl pic. Though I was kinda expcting a Power Glove on one of her hands.
Wonderful job you blended sexy with geek/gamer geek/super-heroine in absolute perfect proportions, I would not be surprised if this became a standard cosplay outfit actually I'm really hoping it does become one. Hope to see more in the future! (If anyone gets pictures of someone cosplaying with this they should post it )
