Apart of my Senior Thesis, this is one out of three rigs that I built.
His rig is pretty straightforward with FK/IK arms, FK spine, and IK only legs. The rig also includes a floating interface for the eye blendshapes and two options for the hands to be animated (hover control with attributes and direct controls).
The toughest part of this rig was probably his skirt. Getting it to deform correctly took time but with the micro controls it's much easier to get the animations to look more fluid. However, for future work on this rig I will definitely be looking into better ways to create proper skirt deformations.
