First I'd like to say you would be AWESOME to star as a live action Sailor Moon; the outfit, the look, and the background are all very well done. Your stance is very powerful, striking, and above all very Sailor Moonish. The Moon in the background is very clear and this all could very well be a scene from a new Sailor Moon Movie...LOL AWESOMENESS!!!
Now for the down side, the boots though well done are too short, Sailor Moon had knee high boots. The outfit is superb, but for the Sailor Moon Super look her weapon was the Moon Kaleidoscope not the Moon Stick.
Lovely cosplay and background though the hair could be smoother. Using a white brush to go over the edges and then a 1 pixel smudge tool could help make strands and make it blend more. Also the background colour doesn't quite match the cosplayer.
