These days I am trying to do some random sketches of human faces. Even though I find drawing facial features interesting but I somehow make mistakes with the proportion, especially the nose. I often struggle with the shape of the lips and also with the shading of the nose.
I started off with light outline of the shape of the face using my Steadtler 6B pencil. Even though 6B is darker comparatively, I like to work with it. When I added contrast with charcoal pencil, it gave a different look to the entire face.
This is how it looked at the initial stage.
This is the final version of the sketch.
