1. Pencil on heavyweight illustration board, sealed with workable fixative and acrylic matte medium.
2. Thin oil color scrubbed over sky with a big bristle brush. To thin the paint I use Liquin alkyd medium and Gamsol mineral spirits.
3. Transparent lay-in continues. It's like a watercolor, but painted in oil.
4. Replace or redefine transparent areas with opaque mixtures.
I use a palette knife to build up the impasto texture in the foam and rocks. By mixing a drop of cobalt drier into the white, even thick passages will dry overnight.
Here's the final painting. Tomorrow I'll show you how I hatched the hatchling.
