This exercise is called Irish Clouds and was the fastest Pike exercise I've done thus far. I didn't time it, but I think it took about 30 minutes. It is done with only two pigments, French UM and Burnt Sienna. I'm beginning to think these were John Pike's favorite pigments as all of the exercises I've done so far have used them. It was done on Arches cold press block, which I'm becoming VERY fond of! This was done without any sketching whatsoever - which was a first for me! Also, I'm using flat brushes and while I'm not as comfortable with them as I am with my beloved rounds, I feel I'm getting more confident with them.
