I love sketching with graphite, it allows a balance of freedom and control which is similar to charcoal. This is a sketch I did for painting in progress. Inspired by the eeie atmosphere of the landscape and woods I had walked a few days ago. I felt a strange empathy with my surroundings.
Studies in oils on stretched paper that I incorporate into some of my paintings. I would abstract these further in the painting or just use as reference to evoke the narrative in the work. Sometimes I am satisfied enough with them as sketched and move just move on to the next.
