After I added all the white patches, I filled in the rest of the body and head with a reddish-brown pastel.

As the face is the most important component of a portrait, I started adding detail there first. The original nose placement made the face too long, so I moved it up some. I had the right eye in the correct place, but needed to move the the left eye down.

I’ve got a good bit of detail done in the face, but after looking at my reference photo I can see that I need to extend his body in the back a little bit. I also want to work on making his tucked front leg a little more convincing before I start adding the final details.
