A great shot! The colours are well chosen and the lightning is exposing. The cosplay is well done and appeals very evil and sexy. The long curly wig gives the model a wild look which matches the rest of the costume. And last but not least: The pose gives the model a wicked and arrogant look, matching the role perfectly.
The only thing I'm asking myself is if another angle would've been better (a bit higher, I think), but then you would have lost the petals hmm... hard decision
