Orc Texturing

Hi all,
This is my personal project. This is a Orc inspire by The Lord of The Rings style.
I scupt this guy in zbrush - you can find the clay render version of this in my previous project.
Then one I do all texture work in Substance Painter, just pure hand painting and proceture, no texture XYZ.
Then I put everything in Maya, do some lighting and render with Arnold.
