Normally, I do all of the cartoon shading by hand, using either brushes, pens, markers or a combination of the above.
For this week's cartoon, I wanted to give it the look of an old-fashioned Popeye comic. I did the basic line work by hand first, using a brush for "Popeye" Steve Francis and a pen for "Olive Oyl" Donna Frye and "Wimpy" Jerry Sanders.
After that, everything was done in Photoshop. I first had to color the characters.
Those flat colors looked to slick and modern to me, so I gave it a basic halftone pattern to emulate the look of a printing press with somewhat sloppy alignment.
Then, to finish the cartoon, I underlaid a scan of some old paper, giving the feel that the cartoon is an old comic on aged paper.
Overall, it gives the cartoon a different look that helps give the vehicle - in this case, Popeye comics - an extra touch.
