Second Update For Today:

Moving along with the painting.  Here I've added the roaning to the neck and will start lifting it in spots.

This is after some lifting and more layers.

Here I've pinked out the muzzle and areas of the face.

Now I've gone back and covered most of the flesh in black with small spots showing through. I'm also adding more layers to the white appy spots on the neck, upper body and face.

Still more layers. She's got a ways to go yet. But she's getting better each time I work on her. (I think)
