I added ultramarine blue in the shadows of the uniform, yellow ochre mixed with hansa yellow in the lighter places of the uniform and I beat the tarnation out of it with a dry, soft brush. I glazed the background with a thin layer of dark purple and as it dried I scumbled a little white into the mix. I glazed the same mixture of yellow around the eyes, red on his hairline and then I introduced the magic...zinc white. I pulled it together and strangely it looks like flesh. It actually looks better in real life than the picture posted here. The strange thing I've noticed about the glazing technique is that it looks better the closer you get to it.
