Just saw this. I believe it is BOTH Nolan. Like Steven, if you are using the edge of the pastel or pastel pencils and are using a drawing approach, hatching etc., it is clearly drawing. If you are using side strokes with large chunky pastels, often with a blended underpainting or an alcohol and pastel underpainting it is very much painting to me and most Pastel artists think that this is the distinction.
