Here I used my blending stump to "draw" in more lines, add more shading to his shell, eyes, face and neck. I blended that area with the sandpaper underneath. is collar and robe I did not use sandpaper to get a smooth effect. I needed to whiten areas like the shell ridges, face, eyes, ridges & piping on collar, and shiny edges on robe. The kneaded eraser was excellent in making these areas light. At this point, I have not used a pencil yet. After those adjustments, I sprayed the picture with "Krylon Workable Fixatif" to adhere the pencil & pastel to the paper for a non-smudging and workable surface.
