I actually like that it's somewhat bleached, but it's a little TOO washed out. Where it's most a problem is her left arm. Just a bit less exposure would be great. Although I have to say that I love the way the mouth looks.
The spots on the wall are a distraction, but those are an easy fix.
Overall, I like the image, and I completely see the "Tank Girl" feel. Vibrant and fun.

This is not so much of a critique, but a personal curiosity: I wonder how this would feel in HDR or perhaps with a Dragan effect?

Devil's in the details...

I like the shot overall, not just because of the model. You have some lost data where it blows out at the front. Natural lighting on skin that pale can do that easy. In this case, I would have shot for a slightly underexposed image and brought it up.

There are some wall details that I think detract from the image and they could have been very easily shopped out. They draw attention away from the image itself and make me wonder "what are those spots on the wall?".

Finally, and very knit picky, her wrist bone is jutting out at a strange angle. Again, distraction, and correctable.

Still, great composure and image all in all. I love the saturated, slightly grimy look you have been doing in your post processing.
