Experiments with black and white are helping to develop form although I do wonder if heavy black was introduced too quickly. Ah, the impatience at times... I'm learning that even with my limited set of pigments that many colors can be reached with simple overlays, especially when selectively applied. For instance, I won't wash over a kernel but only around the edges. Also, that a bit of white makes a fine highlight, as well as a great cover for mistakes.
