In this Image I've pointed out some of the shadow issues I was referring to
Have a look at the two top most green ones, and see the drop shadow cast by her body and arm? But this no corresponding shadow cast by her leg. In fact as shown by the blue ones (on the lamp image) the shadows on her legs appear to be cast by the 'lamp' itself.
The blue ones on the woman show anomalous drop shadows on the red box, one of which obscure the tattoo from being clearly seen.
And Pyraxis is correct the buttocks do appear strangely flat, having little or no definition to them, and no cast shadows as would be expected. The only shadow from the buttocks may be seen as indicated by the lower most blue one.
Wow, that was the image I've (publicly) pulled apart on photoshop before
