Hey There! I finally managed to find some time to finish this guy. There are many things that could be improved or are missing but I really want to start with something new so I will call it done for now.
Thanks to texturing xyz for the great displacement maps and to Alberto Casu (https://www.artstation.com/nexfero) for the great feedback and teaching me many things along the way. As for the softwares I used : Zbrush for sculpting, Marvelous Designer, Maya for modeling, retopology, grooming(xgen), shading and rendering(vray), Mari for texturing and Nuke for compositing.
Hope you like it!
