When I first began Gum Girl I needed to show what the book might look like, so did a couple of try out pages. Here's a very early example using a brush and capital letters in the speech bubbles. The capitals looked rubbish, so I scrapped that. Also, after these test pages I decided against using the square caption boxes to explain what was happening in the story, choosing to rely on what the characters said.
Here's what the page looked like in colour. The palette is a bit dull so we decided to use brighter colours later on. The school is a modern design here, later I thought it'd be fun to have an old looking Calamity Primary that was falling apart. This is also the first mention of villain Octopus Prime. He doesn't appear until August in book 2, Tentacles of Doom!
