Thanks again everyone!
andreja: I did some work on Tsu’tey , I did a pratical sculpt (in clay) but it was changed quite a bit in the end .
Moat and Eytukan . were Photoshop first then worked out in clay then scanned and tweaked in zbrush and printed in 3d again, molded and cast. All the heads of the characters were eventually made into real world painted busts, if I can dig up pics I wll post them.
