portrait of 3 bassethounds pastel second stage

Last night I worked at the front of his face and his eye, not yet there. A lot of things to do, this is only the base. The snout has a somewhat deeper color and his nose is still with no color at all, etc, etc.
I already start to work at the portrait of his father so you can see some of the black ear of him behind his son. Although the father is black and white I will use many many colors to get the black and white. All those folds is fun to do, but to create the shine on his hair is difficult, I expect. But a real challenge. This is a real big project for me, 3 heads on one paper that's a big painting.
