I'm very excited to be putting out Bad Machinery books through Oni Press, starting in 2013. At the moment I'm working on fixing up some of the artork, before adding new pages and making these books less a series of webcomics and more of a coherent piece. Wrestling with that dilemma has been an ongoing thing since 2009.
Looking at these old pages closely for the first time since they originally ran was interesting. They're pretty good, if sometimes a bit dense. There are only a few pages where I was obviously having an off day that need careful revision. It's usually a case of fixing the top of an eye or a head or a chin.
Where I do greater revision, I never know if people even notice. Why not play spot the difference with the page below. The hardest thing when redrawing figures is keeping them on-model - in the very first Bad Machinery story, the kids were all whippet-like little adventure sprats.
