Ok, I'm critiqueing this partly as a cosplay, and partly as a piece of bondage artwork.
As a cosplay, I just don't see how you could improve it, since the costume is just so to the original and the cosplayer looks the part.
Viewing it as bondage artwork is slightly more awkward. I've never seen anyone do something like this before which locks out Vision and Originality. The combination of the lighting, the settiing, the expression and yes the model's considerable good looks give it massive impact.
So this leads me to my one issue with Technique. For me, the shot would be improved by the model's legs being closer to the pillar she's against so that she is bound more securely, and with more tape.
