I did a watercolor sketch demo for a class today and thought i'd share it here. I did it in three layers. First a very transparent layer that's also called a ghost wash. Basically i painted the form of the mouse with just water. And within the wet form i then added paint with neutral colours. The first layer is just light and dark shapes within the form. Then when that layer was dry i came back over it with darker colours to start defining shadows and edges a little more, and then a third layer over that where i defined hard edges where i felt like i wanted them. Most of the sketch is still very loose, i just defined enough so that it felt like i wanted. Then i went over everything with a glaze but left some areas just to give it some life.
