This is the way I do scratchboard. Most scratchboard artists start with a board that is covered entirely with black India ink and and then work by scratching out all the light areas with a sharp knife. I start with a scratchboard that is in it's natural state of white (not precoated with black) and drawing the parts of the drawing that will be less than 50% in value with a pen. Then I block in all the areas that will be more than 50% in value with solid black and draw in those areas by scratching white lines to create different ranges of shading.
I was sufficiently impressed before the addition of cross hatching but that really added a lot of depth and texture in a really subtle way. Absolutely fascinating. Really well done.
