Hmmm, in the scene the unmasked look is pulled from, which only shows her briefly in a couple of shots, she never has that expression. She actually looks much more menacing all through the scene:
Also, although the bridge of her nose is rather accurate, it feels like here it stands out too much in many angles:
I just don't think it's that noticeable when I'm watching her:
Although, to be fair, she looks much, much better here, so maybe in hand it does work:
As it is, though, what with the eyes, the nose and the half smile, I can't help but have the same feeling I get when looking at JND's Chris Reeve Superman. A... JNDized look.
On a final note, her look when Bruce invites her on a date would have been a nice option, too, as she also has that unsettling stare but she's wearing a white fur coat that might have contrasted nicely with her Catwoman outfit.
I guess it's all a moot point, though, as a) they're not likely to change anything at all, and b) I'll probably cave and get the duo version anyway.
