Just finished sculpting this guy. Chavant NSP Medium clay. I used one of the Skull Shoppe's excellent models as a reference. Molding it next for what I hope will turn into a pretty cool project.
Get yourself a set of sculpting calipers. They're like $6. I found I didn't need them as much as expected on this, but there were a few times I compared proportions that really made a big difference for symmetry.Really nice! Your really good with symmetry. I struggle with it quite a bit.
