Human body anatomy study and ecorche

Hi guys,
i finished my first study period at CG spectrum School, i started using zbrush 3 months ago and the main goal was to get confidence with human anatomy.
workflow:
1 sketching primary form
2 sketching secondary form
2 cut the body in 2 half and removed unnecessary part of the mesh ( like ears,skin etc...)
3 posing character
4 making ecorche defining every muscles (visible and not)
5 highlighting muscles using special fiber brushes
6 polypainting the ecorche trying to highlighting the body (WIP)
The polypainting still needs some refinement and can be improved a lot :)
