I used two area lights (main and lateral support for filling) accompanied by a global light and more HDRI for the entire lighting system. I used eight of these for quality and to avoid noise in the projection of shadows, although even six is sufficient (Fig.10).
It is at this point that I decided to render the image in LightWave version 9.6. Unlike previous versions, 9.6 incorporates "use gradient" and "use bumps". These options add additional important details, especially the Nodes fast skin (Fig.11 - Fig.18).
