As for the two previous highlights, the third one can be done using the puddle technique. We only have to reduce the clearer areas again. However, for this particular icon we have used the brushing technique, applying the colour directly with the brush and then stumping it once dry.
Prepare a colour composed of yellow ochre (2/3) and red ochre (1/3), add a touch of chrome yellow and a good touch of white lead. Blend your mixture well and apply the colour on the clearest areas of the face. Apply with a dry brush and be careful not to overload it. Don't worry if there seems to be too much contrast between clear and dark areas, with strong transition. The stumping will fuse the colours later on in the process.
The stumping is done with a mixture of emulsion diluted in 30% of water. Your brush must be almost dry, containing a little bit of this mixture egg / water.
First, as you will see on the video below, apply the emulsion on all the area to be stumped to soften the colours underneath.
Then, fuse the colours with very delicate brush strokes to obtain a soft gradation of tones in the highlighted areas.
Do not insist too much on the same area because you may remove everything after the fourth or fifth passage. Come back later to carry on with your work... If a hole should appear, apply a little bit of your highlight colour, let it dry and stump again.
Highlight all the parts of the flesh the same way: the face and the hands. Once this highlight is finished, and before you apply the last one, retrace all the lines of the drawing since they may have been damaged a little or a lot during the highlighting process. Then, work on the softness of the transitions between the highlights and the first layers. It is up to you to evaluate which parts need to be improved.
