The other drawing, below, took several hours, and I sketched the basic shapes first, beginning with the totem pole, in pencil, and did hardly any hatching.
I understand the whole "drawing is about the process, not the product" premise, but I don't feel a need to choose one over the other. A quick sketch is like a poem, or a journal note to oneself. But I also like to write prose for someone else to enjoy. I think there's room for self-gratifying quickies, but I also like the slow, obsessive attention to detail approach.
