I think another thing that goes a long way toward the realism is the model's face.
It has lines and buldges.  You can actually see cheekbones and the jawbone
and the "parenthesis" around the mouth.  And the nose looks like a nose,
not something a plastic surgeon would make.  The only odd thing is one
stocking top is wider than the other. The toes don't look quite right either.

The room itself is even more realistic. (From the thread I got the idea it is
CGI too)  The bad paint on the trim is an excellent touch.
