This art tutorial on How to Draw a Face using Tone is for Intermediate students. I would suggest students watch my video on drawing a face in proportion https://youtu.be/WROSZ6803cE before attempting this one.
In this video I explain how to create a face by carefully building up layers of tone using a variety of pencils. I show how eyes and the nose can be suggested rather than outlined which makes for a more pleasing drawing. I also explain how the hair can be suggested with a few tones and a few lines. You will also learn that by varying the emphasis on line – light or dark lines – you can suggest edges or areas of emphasis rather than making them look too obvious.
