Painting a face.. Sbs - 4 shadows

Last step before the blending technique
3rd shadow applied just in few places, around the nostrils, eyes orbits, under the chin, close to the hair and fez

This is the "put in place" of the volumes...then I start the blending technique...mainly, I use the same tones but more diluted to create smooth transitions...I use red matte to warm up the tones and black added to skin tones for the beard
