There’s a rhythm to the words combined with the pictures [in a comic]. Whenever I’m working on a comic strip I re-read it, probably hundreds of times through to pay attention to how all of those things work. Sometimes even changing the angle of a character’s eyebrow can really, seriously alter the effect and overall interpretation of a scene. And the insertion of a pause or a cough or a sniff, and all these things that we do in conversation, can bring it to life in a strange way.
