| I'm a wildlife sculptor starting several new pieces for Paignton Zoo in the UK. I'm planning to make two life sized heads of both black and white rhinos, as naturalistic as possible, and specifically not to look like trophies. I'm getting averages for the body lengths but not the head lengths, or widths, and wondered if anyone knows this? I'd be very grateful for the information. Enclosed is an early stage of the maquette, (small model), of my Black Rhino, showing off that wonderful prehensile top lip.
