The
nose is formed by a series of curved planes. This makes
it difficult to draw as there are very few lines to help
us describe its shape.
Start
by drawing what you can see, namely the inside and outside
edges of the nostrils. Then try to outline the main areas
of tone that define the planes of the nose.
Draw
these lightly as you want them to disappear under your shading
at a later stage in the drawing.
Step
2 - The Initial Tones
Simplify
your shading into three basic tonal areas - dark, medium
and light (the white of the paper).
Block
in each plane of the nose with its appropriate tone. This
should begin to render its three-dimensional form.
Step
3 - The Final Tones
Carefully
refine the strength and subtlety of the tone, softening
the lines that join each plane with graduated areas of
shading.
You
must look more closely at this stage to try to discern
the faint variations of shading within each area of tone.
