This was my entry for Sketchfast 5 (72 hours time to create a Pixar-like monster)
Contest: http://blog.sketchfab.com/post/52953410943/sketchfast-5-monsters-university
It was fun and I improved my sculpting skills at Dynamic Topology Sculpting.
Dynamic Topology is awesome to bake textures :)
For the facerig I used a lattice in combination with the armature.
After the contest I've improved the rig and for an easy control I added some Custom Bone Shapes.
