These were all originally photographs (with the exception of the Mickey Mouse). When I was taking my Photoshop class I would screw around with the smudge tool a lot. These are some of my favorites.
To be quite honest, when I first drew this a few years ago I was not trying to make a political cartoon. I just had a dream with a beardy man’s face smugly creeping out of a horse’s rear end. So to answer a question I get very often: yes, sometimes these things just come to me in crazy dreams.
