Lovely study. I'm so drawn to the way you made the whitest highlight disappear into the white background. I had a vicious drawing master when I studied life drawing at university. But he made us keep a journal in which we drew nothing but sketches of our own hands and feet. I've thanked him, mentally, for that many times over the years.
