1. Draw the coiling curves. Curls have to be different size.
2. Draw the second layer of curls over the first.
3. Make curls very dense structure and very dark.
Now we will use various softness pencils.
1. A pencil 2H we create the first layer of curls, from above it the second layer.
2. A pencil 2B we draw the following two layers.
3. A pencil 4B we create black tone.
4. Create a scale and draw these options from light to dark, then on the contrary from dark to the light.
Here example of use of various shades.
Here use example when drawing skin at the child of a gradient of shading in the form of curls.
Here an example of drawing of trees by means of them.
Now we will try to draw a gradient.
Pencil 2H we draw the most left area, curls have to be the big size and light, then we take a pencil of NV and we put curly curves, the closer to the middle, the more densely.
We draw NV a pencil almost up to the end, then we take 2B and from above we put new curls very skintight to each other.
We draw up to the end very densely to the friend rounds a pencil 2B, then we take 4B and we put from above curves, right at the end it is almost not visible white paper.
Try once again transition from light to dark, then from dark to the light. Then draw ringlets very small that the background was rough. Stretch ringlets across, doing a gradient from light to the dark.
