The cosplay looks really elegant but at the same time, it has a tough girl look. The cosplay is based off the anime and the amount detail put in to this costume is immense. You captured the character perfectly. There is, however, one thing you did miss, it would of been great to include the yellow eyes. The old fashion style is just great!
The Materials you used were of great effect. the straps were cute, sexy and beautiful. And you certainly have the figure to pull this off. The pose you used for the picture is excellent; very cute :3.
