I usually like it better when her costume is made out of shiny leather (like Catwoman's in Burton's films) but this is a very pleasant image (despite the lack of shine) and she looks incredibly sexy! Awesome job!
Just solid. That's the first thought that crossed my mind when I saw this. Nothing flashy or over-the-top, but just an image where a mere glance of it tells you everything you need to know about it and is able to leave a positive impression right then and there.
The snow-white hair, the soft skin, the body-flattering suit. Every area is just done with a level of execution that appears pinpoint and is instantly captivating.
Can't really say much more than that, and quite frankly, it would probably be saying too much if I tried. Awesome job!
