Here are a few figures I'm working on. This is the basic stage where I've just added underpinning to the metal armature. One is going to be a body matrix so it isn't posed.
Underpinning is essential to all sculpting, it gives you underlying musculature, a base to work on so you have support, and adds depth to any shape you are sculpting.
As you can see I have basically added the underlying musculature to bulk out the figure. I will add details on top of the underpinning later. I always sculpt from the "ground up" so you can see I've started the footwear on these two first.
