Armature for Hands
Add some hands to your wire armatures. This is usually easier if use a thinner 20 gauge wire for the hands and fingers.
If you only have larger 14 gauge wire, you can do a larger hand study and build out a section of wire just for the forearm and loop of the palm. If you do this remember that the distance from the elbow to the end of the loop of the palm is 2 cranial units.
