I went over an image of Bart Simpson in Illustrator to learn how the pencil tool works. I was somewhat use to the tool, but didn’t realise that by clicking on the point you are drawing from, it will change the curve line back to a straight line, which is really good to know.
The image consists of 3 background lines drawn with the pencil tool, 4 ellipses and 4 lines on the forehead drawn with the pencil tool. Illustrator seems to be a quick way to draw an image over Photoshop.
