I thought that the most difficult part of this drawing was getting the shades of white to blend together. It may not show it in the picture above, but I felt like my shading was kind of choppy.
Yes I was able to create a full range of value in my drawing because I drew the airplane from an angle that shows all values. My darkest-darks showed where the folding was in the paper; the paper that was a flat surface was my lightest-lights. Drawing my lightest-lights I think were my strength in my drawing because it was easy to get the light value using white charcoal on a black piece of paper.
