I don't think basicwiz meant it was Anastasia but rather that Anastasia's feet and toes have been so well-sculpted that they can look as realistic.   Otherwise the first image is definitely photo-manip.   The second one does look more 3D and you can see her legs are not the same as in the first.   Sometimes artists choose to clone in various details from photos so the base may be 3D but with cloning over it.  

In any case, if you'd like to make V4's feet more realistic I'd suggest you pick up these toe and feet morphs:

This set by Fabiana also has some nice leg morphs as well:
