the basic linework can be generated by the poser edge-blend node plugged into the ambient channel, then augmented in APS with the pen tool and paths.  poser itself can do dramatic shading and coloring, almost as good as a pro artist, but the differences are easy to spot.  if it's a pro colorist with 10 yrs experience, no need for poser shading, but anybody still learning how to draw or paint should leave the shading to poser IMVHO.
