One criticism I have about the art is that all your characters look about the same size in each panel. Vary it a bit with some close-ups, distance shots, even a silhouette or two, etc.The strip that follows is my feeble attempt to follow his advice. I was also inspired by a very handy comics creating resource I had remembered seeing called "Wally Wood's 22 Panels that always Work!!"
This fantastic resource gave me some great ideas for practical ways to mix it up a bit.
This comic strip will appear in an upcoming issue of Hopscotch magazine. The theme I had to create a comic for was "Riddles".
