I started to paint the face by paying attention to the values and temperatures of his sculptural shape.
The photo shooting was done under a very strong sun light in front of my studio so the light catching parts were bleached and the shadow and shade areas were almost black out that I purposely lightened the values and the temperatures of the areas. Not like opaque sculpture, some parts of the human face, especially the ears, are semi-transparent. It is more influenced by strong light source.
See his ear and nostrils on his right.
The canvas, clear-medium texture linen was washed with diluted paints in the the same manner as watercolors and I sketched with rows of monotone umber.
