Is it finger, tortillion or foam you used in blending?? For I know I know tortillion and foam to be good blending materials but the disadvantage of both of them whenever I blend is that it doesn't retain the value of the charcoal or pastel tone. It makes it look brighter. But for finger, It even makes it darker and even. But by the way, Your black and white drawing is so nice. Just as nice as your coloured pastel drawings. Watching you make the drawing was so satisfying to watch and I am like "Oh so this is how it looks when I draw too" haha. You awesome. Keep doing art.
