The above image is my current latest character model, created only a month or two ago.
As such, it's the culmination of all my rigging knowledge.

The bone colours aren't all that important but I did want to do it anyway cuz it looks cool.
The model features Inverse Kinematics for the legs and waist, rigged eyes and pupils, and a lot of shrinkwrapping.
My least favourite part of character modeling is joining up all the parts, so for this model, I used the shinkwrap modifier many times to mask joints being disconnected.
