Colors not all there yet but this is just one layer of glazing in most spots. The far right edge has two layers of Indigo glaze and I'm going to experiment with a few more to see how deep and rich I can make this dark shadow. One of the things I'm going to try is glazing a layer of clear medium between each layer of pigment glaze - to try to heighten the optical illusion of peering into some depth.

In the highlight areas I want to get more color as well. Initially I'll do that by glazing but ultimately I'll replace the glaze with a thoroughly opaque equivalent.
