Sketching Now Lesson 4 we looked at constructing volumes. Trying to develop eye and hand coordination. Needless-to-say, my hand did not want to co-operate. I think I must of drawn this stack of books at least 20 or more times. Perspective drawing has never been my strong drawing skill; I tend to struggle with getting the angle correct. It wasn't until I just looked at the volumes of the books that I finally was able to get a drawing I could live with.
