Have you heard of Skullgirls? It's a fighting game, which came out for XBOX Live Arcade and PlayStation Network a few weeks ago. Its characters have an interesting design, which might be a challenge for a wonderful cosplayer like you, for example: Valentine (who has the same fighting stance like Mai) or Parasoul. What do you think?
Nice photo. The girl is a little bit in the centre, and her clothes are a bit cut off on the right side, but what i really like is the contrast between the red color and the fore-background. The model is also beautiful and i see, you did a good skin retouch work. Summary: very good
