Thanks for comments friends!
The mix for flesh tones is difficult to say... everything in this bust is painted with oils. For flesh i used titanium white, venetian red and gold ochre for base. Light with napoleonic yellow and titanium white. Shadows with burnt umber and burnt sienna. Medium tones with cadmium scarlet and magent. All colours are artist series of windsor and newtom.
Cheers,
Nando.
