The Overall Idea of this character is mix of Troll, Giant and dwarf as you can see it from proportion of the body.
All the Body details and props of the troll are Sculpted in Zbrush,
Except from displacement map Most of the Maps done in MARI.
For hair - its Xgen core and Arnold for final renders.
Hope you guys will like it.
