Before writing this critique I made use of some Wiki-Fu to research details I wanted for the text.
I know that the cosplayer sees herself playing the Julie Newmar (Batman Tv series 1966-67) version of the character, who never appears as a "civilian" alter ego. That's why I marked "Originality" down to 3*; it's been done before.
Vision, Technique and Impact I marked way up, because I was impressed by how well she carries an iconic role (and personally my second favourite live action take on the character after Michelle Pheiffer's in Batman Returns).
There are 2 slight negatives:-
1) Julie had shoulder-length straight hair in this period rather than a tousled bob, although the bob suits both the character and the cosplayer.
2) The Tv series character did not use a whip.
