"So we are going to be moving on here with another small round brush and I have some yellow Ochre. I am going to use yellow ochre to apply here down in the neck area. Basically, what I am going to be doing is I will apply a little bit of it and then it is going to be all about blending. What we want to do is the yellow ochre is going to be the deeper colors for this face. You can see I am just kind of going back and forth and then winging the brush out trying to avoid any sharp strong lines except for right where the neck meets the interior of the collar and that is fine. That is natural. Like take for example over here on the other side of the neck. It is pretty faint. Come back over here up against the line. And again we have the line of the neck is nice and drawn in. Just drawing in this yellow ochre and blending it for more skin tone. The effect we are going for is slightly spotty and a little freakier, almost like a quazi-zombie-ish effect for this alternative portrait. Other skin tone effects you are again just taking the yellow ochre and mix it with a lot of media. At first I almost just kind of drape it over the lines I have here, down over the nostrils. At that point then I get rid of some of the media, make sure my brush is a little drier. Now it is all like kind of extending and softening these lines. Kind of getting them out and around to create the impressions of the nose and skin tone. We are going to extend this effect throughout the rest of the face expanding out from these core lines and to shade in and add emphasis on other parts of the face."
