Hail Noble Lords and Gentle Ladies of the Court!
I tried a variation of the technique using lighter flesh tones, but didn't get the rich details like the photos. It was a female face I was painting so I had substituted bronze flesh for the dark red, but maybe it wasn't enough contrast with the pallid flesh dry brush I gave her. But I am encouraged by the tutorial because you can't argue with the author's obvious success, so if I keep trying this technique, I know my models will start looking much better soon
Lol, it's true the final photo is very ferocious looking, but that's so appropriate! I rated the article a 5 because it's a simple but effective way to paint faces that produces a lot of detail, but doesn't require painting in shadow and picking out highlights, which is very tough for a clumsy person like me.
Sweet Saint Repanse smile on you!

P.S. Anyone have any pointers for adapting this technique to female faces?
Hobby 
Start with a clean, flash free figure.
Prime the figure black. That's right black, you will see why in a moment.
Dry
brush a very lightly a coat of white on the figure. Use only downward
strokes, not upward strokes. This will highlight the figure in white
but leave all recesses black so you won't have to black line anything.
Dry brush on a layer of DARK reddish/brown, using only downward strokes.
Dry brush a layer of dark flesh on the skin areas, again only using downward strokes.
Now
get out your lighter shade of flesh, or mix your flesh color with some
white and paint the following; A line down the center of the bride of
the nose. Two dots on each side of the nose for nostrils. Two dots on
each side of the chin for that manly cleft. A line along each raised
cheek that turns down towards the sides of the mouth. Two lines above
where the eyebrows will be. Highlight the earlobes. And finally, a line
along the jawbone.
Now
the eyes and the mouth. Paint some Gore Red in the mouth cavity. Lay
the figure down so it is steady, and resting your hands on the table,
paint two light grey stripes where the eyes will be. DO NOT USE WHITE!
White makes the figure look cartoonish. (Get a piece of white plastic
and hold it up to your face while looking in the mirror, you will see
that your eyes are not pure white, but light grey.)
Mouth:
Take your smallest brush and pick out the teeth in skull white. Eyes:
When the grey is dry, again resting your hands and figure on the table,
paint a vertical stripe of blue over the horizontal stripe of light
grey. (You could also use green or light brown for eye colors.) Don't
worry if your vertical line hits the eyelids or cheeks, it doesn't
matter. (Notice that I hit the eyelids & cheeks a little myself, it
will be covered-up in the next step.) If the first stripe you paint is
not in the middle, let's say it's to the right a little, that's ok too,
just paint the other eye stripe to the right a little as well & the
figure will look as if he is looking to the right. The only thing that
matters is that they are similar.
Ok
it's time to cover up our little errors. Get your finest, smallest
brush. (I use a 10/0 brush that has only 20% of the bristles left.)
Paint a line of black over the top of the eyes, covering any of the
vertical stripe that went too high, this line will be the eyelashes.
Paint a line of your original Dark Reddish/Brown under the bottom of
the eye covering any of the vertical stripe that went too low. This
line will serve as the lower eyelid/socket and will set off the eye
very well. Paint a black line for each of the eyebrows.
Finished
