Scientific Illustrations

Most of my illustrations where done between 1976 and 1984, although I began drawing again in April 2006. The vast majority of these were done with a combination of colored pencil, inks, and watercolors. The bulk of the color came from colored pencils, with inks and watercolors forming the highlights and shadows.
