Before laying out each issue with Photoshop, I first create a storyboard on paper. Most of the time these storyboards are created at the local pub with a couple of friends. As you will see, my artistic talents are non-existent in these storyboards (and the beer at the pub doesn't help either), but they're really used to help tell the story, and see how it lays out from page to page.
After looking over the storyboards, I'm surprised at how close the final issue is to the original storyboard. I got a big kick out of comparing each page to the original, and I thought you would too. I've scanned each image as a greyscale jpg at either 100 or 150 dpi. Image sizes range from 36K to 275K.
What's also fun to point out are the other scribblets on the paper that have nothing to do with the comic. You can see, for example, the name Mark Laidlaw on one of the pages of issue 5, which is roughly when the guys at Valve called me up and asked me to do an issue with them. Another word you might see is 'TCAHCMEKE', which is an anagram for CHECKMATE-- part of a puzzle from Tex Murphy: Overseer.
So, enjoy the drawings, and forgive the chicken scratch!
