Here's a recent commission. NOT a watercolor. My client requested charcoal. I started out by blocking in the dark using 2B charcoal pencil and worked my way through 4B and 6B to get even darker. I also worked all over alternating between the dark and highlights and then I'd squint and go even darker or lighter.This little doggie also had some bits of brownish/red in his fur so I pulled out my flesh colored conte sticks that I use for figure drawing. Those added a little bit of spark.
