How we can make a wax sculpture?

The first thing is to choose a character, then for the face, there are two ways to make it:

-directly on the person

-or by modeling the wax just like a scultpure

Then in a mold of gypsum we put melted wax, and then we start with the details, eyes and teeth of crystal. The beard and hair are so difficult to put because we have to put it one by one.
