Hi Ian, you are brave than me, I also was thinking about such loose watercolor experiment to let the color flow and to mix with other one to create a natural mix but still did not reach that moment. I never thought of idea of using minimal colors but that on other hand depending on the quantity of water and pigment may also bring the different colors as primary colors we can create other from then.

I like how you have done eyes, they have such depth and viewer automatically concentrating on pupils.

I am glad you started using watercolor there is so much potential and discovery, would be nice to see your further works :)
