This is a sculpt I made for 3D printing.
It is based on the Yoda drawing by Piper Thibodeau.

Sculpted in Zbrush, Rendered in Maya using V ray.
(Super simple poly-paint, I used this plug in to transfer the
poly-paint to Maya: http://www.zbrushcentral.com/showthread.php?188919-Polypaint-importer-plugin-for-Maya )
