The neck
The first thing we’ll do is add more resolution to it, either by adding more subdivisions to the Multiresolution modifier or by applying the modifier and re-meshing it at a higher resolution so that we can shape it better. We kept the modifier and set it to the fifth level of subdivision.
Let’s start with the sternocleidomastoid muscles, which extend from the back of the head to the clavicle. They are less visible on the sides of the neck when relaxed but become more visible as they get close to the front. These muscles can be more or less apparent depending on how thin and/or athletic the person is. We are making both base meshes in relatively good shape so they will be slightly more apparent.
Using the Draw and Grab brushes, we can start adding volume to the area, roughly shaping where the muscle should be. Remember to keep symmetry enabled.
