Thank you, everyone. Progress has stalled a bit as (real) work has picked up lately and I've been distracted by my plan to build a a set of human figures. Quite a complex process, I've learned.
Here is "man02." Better mesh than before – I'm learning to plan for joint deformation – and I'm getting some practice adding hair in Maya. I think I'm happy with the level of detail – he will never be placed this close to the camera in an actual scene.
This is a standard render. It looks much better with the path tracer, but the eyes use a glass shader and turn black.
