Faces are everywhere. They are unique but similar at the same time. Drawing faces can be challenging. It depends on your expectations and goals.
I like loose and expressive drawings that capture the essence of a person.
I watch a lot of TV, and I have started to look closely eyes, nose and mouths. It is a fun challenge to do quick sketches of these features.
A really fun project is to do hair portraits. It is simple and satisfying. You can use magazine references and other photos. Sometimes I feel like the hair alone can capture the essence of a person.
If you are struggling to see the nuances that characterize a certain face, then you could do a tracing. I am always amazed at how much I can learn from tracing the dominate lines of my face. Tiny differences in line placement can make a big difference in accuracy of the drawing.
Tracings can feel stiff and without energy. So I try to use them as a tool to help me to see more accurately.
This skill of accurately seeing carries over into drawings of all types.
