For this study my focus was on:
Exploration of edges - soft, sharp, broken etc.
Composition using minimal number of values - I pushed the values close to each other and combined them whenever possible. I also omitted some values. For example, I did not paint the highlights on the cup. The highlights would have introduced another value and would have disturbed the quietness of the composition.
Somewhere along the way, I decided to include some purely abstract shapes into the painting. Because it was fun.
