The hands would not be as laborious to rig as the female model that came with the tutorial, primarily because I only had two big fingers and a thumb to rig.
Once that was done, I now had to parent these fingers to the wrist to make the hand. In order to emphasise the grip in the fist, I decided to add an extra joint, called the leftHandPalm, which is marked by the pivot here. This should hopefully make the range of movement in this hand greater.
demonstrated a few posts back.
