To keep survey of the numerous surface areas one starts with the definition of the most important outlines.
Later those outlines can also serve as lines of intersection for other elements. Therefor the "Bezigon-tool" is useful to adjust the nodal points in a precise angle.

The first details will be worked out and therefor double the number of areas to approximately 500 forms. The "brighter" and "darker" color areas will be determined and worked out.
If areas might overlap, they should be cut to separate.

Now the finer details will be depict and modest gradations implemented to intensify the three dimensional impression. Shadows and highlights will be placed into the eyes and on the lips, as well as teeth and fingernails get a shine, to achieve a more plastic and vivid effect.
By now the number of areas has once more doubled easily to now approx. 2000.

The background will be set on an own layer and shifted under the exsiting one. The upper layer will be closed to prevent involuntary displacement of the embedded elements.
Now it´s possible to create the background without having an impact on one of the other layers.

Are all paths in position, it´s time to create the color chart. From the main tones 10% nuances will be set. So, that especially the skin tones are appearing in a less strong "step-like-pattern".

From now on everything is allowed which serves the intended effect; color gradients, lenses, outlines, etc. Despite the fact that all forms are cut, one still has to pay attention about which forms are overlaying.
It might be helpful to put all highlights on a new separate layer.

My current illustrations consist of approx 5000 forms.
