Trying to draw the paper airplane was difficult, because you have to try and draw the dark spots, and the folds. Their were a lot of dark spots on my airplane, that I had difficult drawing. Creating a full range of value with white charcoal was difficult. Looking at it from the picture it looks like there is a lot of the same color, but looking at the actual drawing there is different values. The thing that worked best in my final drawing was being able to get the right angle and making sure there was the right amount of folds, and creases.
