Instead of trying to sculpt from scratch, I\'d work on conversions instead. Just change the pose of a snotling to make it crouch, then stick its nose into the dwarf\'s belly, as though chomping off a piece of liver. Or for one with an open mouth already, lift it\'s head, put a bone in one hand, and move the arm as though the snotling is ripping meat from the bone.
Conversions - much less effort and hassle than sculpting from scratch.
