I did this comic a few months ago when I was teaching myself to use gimp. I'm thinking I might try to animate it.
I'm not sure how I am going to show movement of the actual guy. I might have to creat three to four images of him walking and cycle them although i'm not sure if I can do that in After effects. I might cut off the bodies at the stomach and just have him move across the bottom of the picture bobbing up and down. In the end I would like to have the audio of the text follow the animation but we'll see.
Here is the full comic..
Here is the frames for the guy walking using dan's idea.
