Icestorm posted this sculpt and breakdown on Blender Artists. This was my recent collaboration with ColiN00B. This took us extremely long (60h) to do. Mainly because we had a lot of trouble finding a good composition. Done in Blender Cycles, Zbrush and Gimp using lots of awesome textures from Poliigon.com. Rendered with 2500 samples.
