As the finished sculpture is not an ecorche study, I am not concerned with making every muscle with attachments and origins. My goal is to lay in the shapes and forms of the muscles that most effect the surface.
I am using Chavant's Clayette in Hard for the skeleton and hands and Clayette Medium for the muscle mass. I will also use the hard for the face and hair as this is a small scale piece.
You'll notice that the hands look a bit big in the beginning. This is because there is little muscle - mostly bone and tendons in the hands and feet whereas the legs and arms have a lot of muscle and fat. When you strip the figure of a lot of the muscle and fat - the hands will look larger in proportion to the overall figure. As I flesh out the rest of the figure you'll see the hands and feet will look more normal with the larger forms of the legs, arms and body to balance things out.
My husband just walked by and wondered aloud if all this skeleton and muscle work was necessary and wouldn't it be easier and faster just to glob it on? Short answer - yes and no. Sometimes I do just jump straight to large masses (outer form of skin) and quickly set things up. But taking the long road (bones and muscles) does things for a piece of art that just can't be achieved any other way.
