shading rate of 0.02 might be a waste of resources for this image, but give it a try. at least 0.2, anyway. in the old days, it was simpler - one would just "anti-alias" the image, but that was seen as too physically simplistic, so they dropped that terminology for ray-trace renders. but it's a bummer when folks say to turn bounces down to 1 IMVHO. not that it matters in this example (more than 1 bounce would be a waste of resources here), but that is one of the reasons (in addition to giant boobs, no background, bad joints and no shadows) why most of these renders have the telltale "poser look".
