For something a tad different, here's a quick comic presented in glorious black and white! Okay, actually with this one I'm going all classy and trying to imitate the style of magazine cartoonists from the forties and fifties. I'll leave it to you to decide if I succeeded at aping this style, since you're all no doubt familiar with the oeuvre of Hank Ketcham.
It's a great maddening exercise for working on your inking skills, since you can't fall back on coloring and shading to hide the flaws or help it read better. Really, anything that makes you feel like a fraud is gonna help your art in the long run.
