Over the years his expression became confined to one of loathing, disdain, & disgust.
I tried something new with this sketch. After I drew it, I taped a piece of tracing paper over the sketch and inked the tracing paper. I think the results are decent, but I could do better. The heavy outlines are too heavy for the size of the sketch. Some of the more delicate linework from the sketch got obliterated. At first I was laying in the hatching very slowly and that made a heavier line, but once I started working quickly, the hatching looked much nicer. I'm not going to go back now, but I should have hatched more on the left side of the face to push it back more. It competes too much with the nose.
