Hello hello! It's great that you want to learn each element of the face separately. What can be easier for learning is replacing organic human forms with more simplified, geometric versions. Cylinders, spheres, squares and triangles will be your best friend in learning how to build a human face (that also implies to other subjects). Start by using the Rilley or Loomis method. These are dependable methods for facial construction. We should first make a circle to use as our base. The next step is to draw a center line around the circle in both vertical and horizontal directions. This can be done from the side or the front. The eyes, nose, ears, and mouth are the next significant facial features that we highlight. Placing some basic forms for reference is another method that I find useful when making the head. Circles stand in for the eyes, an upside-down triangle for the nose (I like to think of the shadow the nose will throw), a little "M" for the upper lip, and a small "U" for the lower lip. Depending on the angle we select for our face, each of these elements will be portrayed in a different way. Therefore, it is crucial to understand how to design faces for any viewpoint using basic geometric forms before going on to more realistic looks. In general, they are simpler to learn and operate with. Put the style you want to emulate on top of a solid base! Hope it helps! Happy learning! Keep up! | Artwod Feedback
