As you can see from Peanut's photo one of the eyes was clear and one was very much in shadow so I enjoyed the challenge of making the right eye reappear, using the left as a reference.
White highlights show how the beagle has aged. At this point (below) the drawing looks almost done!
The final touch is the shading on the white parts of the dog, making the dog look three-dimensional in this area too!
I think Peanut is pleased with his portrait!
And so does his owner!
