I built a base mesh (as always) in Maya using SubDs..
There's still a fair bit to do, like his elaborate crown/tiara (he's the last emperor of Byzantium) and the raised Greek lettering on the coin.
I've made several attempts in Maya to do this project over the last few years and failed miserably. This time it worked the way I wanted it to. It was really difficult to figure out the way to do bas reliefs like this in a 3d program. At least it was for me.
15.6 million polygons.
