Nice job with the fishnets for one thing. I do love the gorgeous flesh toning and detail. Her eyes are gorgeously done as is her outfit coloring and background design. Love the realism in her facial work and hair layering. Nice touch with her shadow to accent the awesome lighting job.
Love it! Not because of the drawing, that is great. Not because of the character, that is one of my favorites. Not because of the costume, that is hot as hell. What I love the most about the picture is the attitude she is showing and the way she establishes a relationship with the viewer.
