When I wanted to start with the UV in Maya, I find out that I had a lot of spirals. And the topology was not straight. I went back to Zbrush and with the ZRemesher and with the use of guidelines I made the topology better. I took me some time to make the topology good for his face. I wanted to make it optimized as much as possible for the rig and animation.

I made a circle around the mound and eyes. And I followed the curves of the face to finish it. For the body, I made a circle around the arms, legs and belly.
