I've got a draft of the rig that I've sent to Nicholas. Here are some screenshots showing the setup.

Reverse Foot Lock (joints hidden)

There are still several issues I have to work out, as I told Nicholas. They are:

• The hands have rotated strangely because of the elbow pole vector - I haven't been able to fix this yet 
• The thumb ring controls will not align the way the others have, I need to fix the orientations here or something
• I would like to add an IK/FK switch (the rig is currently only IK)
• Potentially add finger controls to select the whole finger (an easier way to do a finger curl)

Also, I have not yet skinned the character. I'll work on that after I've gotten the rig more finished.
