Thanks to some very helpful guidance from my drawing instructor, I learned how to draw the nose and “presto!”, Zip has a complete face! The nose was done with an ebony pencil and the key was getting the values right by working over the area repeatedly. Finally, the paper texture was helpful in giving the nose that dotted/pitted look of a dog sniffer. Never saw that coming, but apparently it’s a reliable trick.
Worked some more shading on the darker side of the face and the paws. I’m guessing one more session should finish this up.

NIce job. That’s a difficult subject to draw.
