The good thing about having another job

I wouldn't like to do the kind of illustration where they say, 'We need it for this afternoon." Sure, I could do something.

But it's much better to work on something off and on. Your brain can be thinking even when you're doing other things. Like walking along the road (hope I didn't startle the girl behind me too much when I suddenly waved my bag in the air and exclaimed, "Ray guns!") Or dusting, or mopping a floor. These things don't take up all your brain, and you can get a lot of useful work done then, instead of staring blankly at a computer screen.

Mid-mopping break to get my thoughts on paper.
Really like the sketch, unfortunately doesn't work so well when I do the actual illustration :-(
