Yes, it does look plastic-y, especially her headband and the gold accents on the bustier; would it be so hard to use actual metal? Getting rid of the shine and making the blue a couple of shades darker and the outfit would already look a lot better.
As for her, I've seen a few people complain that her face looks pudgy, but I think it's the way the hair frames it that's doing that; there's something weird about her hair (I can't quite put my finger on it).
The bigger problem is that she needs to work out with Jessica Biel's trainer from Blade: Trinity; she's supposed to be an Amazon and it would help if she looked as if she had muscles.












Could the entire costume look any more plastic (breasts excluded)?
