Okay, so I went all around the perimeter of this drawing first, working from a photo, and showed the result in my last post. As an exercise, it was fairly amusing and I really expected a pretty goofy result (well, a much goofier result at any rate ... maybe next time) because I thought I would probably be further off in more parts than it turned out I was.
When you work from one side to another or all over the page, you have multiple internal checks for things lining up, being at the same level, coming together at the right points or leaving a certain shape in negative space. Here, the only negative space was around the shape and under the guy's right arm.
Next time, maybe I'll try a more peculiar outline. Maybe next time I'll try doing a still life (or something else able to stay still long enough since this takes a little while). At any rate, it livened the routine up a bit for me!
