This drawing of a human face was sketched with pen and watercolor pencils.

Human face drawing, pen and watercolor

I started sketching an interesting pair of eyes, and then expanded some shadow down to the cheek bones. At that point I was close enough to the semblance of a human face, so I added some watercolor pencils for color. After a few washes I let the water dry where it may. Here is an extreme close up of one side of the face.
