Tried to make the Atelier Acrylics behave like the oils used in a previous workshop… Did not work… had to layer. Started out with a Naples yellow underpainting… followed by "grise" done in Burnt Sienna and Brown Black. Overpainted with flesh tones made from various combinations of Red, Permanent Alizarin, Yellow, Sap Green and white… Used tinting white instead of Titanium and ran into problems with highlights, but not overstated. 5hrs painting. Original drawing from photo took 2 hrs… used method suggested by Aristides.
