I have a tendency to like to overwork things looking for just the right line. So lately I have been forcing myself to be a little more sketchy. I gave myself an hour to do this warmup sketch of Briareos from Appleseed. The guns were the last thing I drew and the hour was almost up, so they got shortchanged, sorry.
This kind of drawing is fun, because my goal is not necessarily to make a good drawing, it is just to finish before the time is up. The time limit removes most of my edits from the process. Its like when I was drawing as a kid, I didn't know what made a good drawing or bad drawing, I was just drawing to make a picture, to create something with pencil. The process itself was the joy, not the quality of the finished drawing.
