Put down an under painting with watercolor. I decided to use that instead of acrylics because I have better success with it's application on this Epson watercolor paper. The only thing I haven't painted is the clump of small berries. I think I should darken the hair, helping it to come forward and distinguish it from the branches. After that, I will seal it with an acrylic matte medium and proceed with the transparent layers of oil.
