Shading and tone... lots of information in how to add shading and tone
Now shading and tone has been added all over the face and areas have been blended with my finger like across the nose. Notice the tonal variety here, the blended softer areas across the nose to the harder edges of the bony sides of the nose and the same with the cheek areas.
Stand back and look at your drawing to see what needs to be done, one mistake some amateur artists make is trying too hard to get a likeness. Forget all about a likeness until the very end of your drawing and instead try to concentrate on the structure of the head and features in relation to each other, get this right and you will automatically get a likeness. Half close your eyes and see the tonal variety in the shading in this example.
Here the actual eye shapes have been drawn in and using a putty rubber the whites or in this case the greys of the eyeballs have been lifted out, in this example I am carrying on with more work on the nose.
Here I am holding a pencil vertically against the left corner of the mouth to see the vertical alignment to the left eye and I have also started to add a bit more tone under the right eye and a little more work on the top lip.
See how much darker the portrait is now becoming by adding shading and more tonal variety to the whole eye shape, it is the building up of tone that gives the portrait depth (adding layer after layer) the cheek and also the corner of the mouth are now coming into play with dark areas.
More darks to the lines of the lips have been added giving them more shape and here I have exaggerated the size of the mouth more and I don't really know why I did this but I like it and its my drawing so there! I've put in more dark areas under the chin area and I hope you can see the variety here both in the shading and in the line, some of the lines are really dark, some are light and some in between, also look at the different thicknesses of the line.

Here I am pulling out charcoal with the putty rubber to make medium tones in the portrait and also to pull out an highlight or two on the lips.
I have drawn in the highlights in the eyes with a white pastel to make them sparkle a bit more, I could have left white paper here for the highlights or pulled them out with a putty rubber but I preferred to actually put them in with a pastel.
