This is one of my first etcings that I did while I was in school but still really like. I like the tones even though I didn't use any aquatint! There is some plate tone which adds to the effect. My teacher liked the way the dark spots came out on the frog - looking fuzzy and almost three dimensional. I'm sure that I etched those areas in the nitric acid (what we used in school at the time) for quite a long time to make the lines very black. Anyway, linework can be very satisfying!
