I was thinking that sometimes as an illustrator you get so caught up in a style that you forget to just draw. You forget to draw what you see, and not in the "look" that you've developed for your work.
I wasn't trying to make any sort of a good drawing while I was doing this sketch-- in fact, I didn't care how it turned out. I just wanted to observe the forms and the distances and get them down on paper. It was very refreshing not to have that little critical voice perched on my shoulder!
