Painting fur can be daunting if you don't know what order to put down the colors. I started out blocking in the fox shape with a transparent red oxide. Using a tiny grass rake brush, the various shades of earthy reds were worked, layer upon layer. The highlights were last.
Talk about tiny! The pups' heads are only about 5/16th of an inch.
After it dries, I will coat the painting with Galkyd medium. It will give it an even gloss, and because it is a painting medium, not a varnish, it can be applied over paint that has just dried. Varnishes can only be applied after about 6 months of cure time. Galkyd also deepens all the darks and brings out the brightness of lighter colors. Below is Fox and Fern, which has been coated with Galkyd.
