A month ago I had a dry stretch during my off-month of not working on Prison Architect, and the conversation came back to me. I decided to do some research on ebook authors, and see if there was a market for cover artists, and it turns out there's a pretty big market out there. I don't know why I hadn't thought of it before, especially since I'd already previously been approached by an ebook about doing his cover (time was a little constrained back then, and I made the decision not to pursue it).
I failed to realize it before, but now I understand that the Kindle and similar ebook devices have created a booming market in self published books in the same way that the iOS devices created a new market for indie game and application developers. Of course books have become such a niche that this market is inevitable much smaller than the app and games market, but this was still an untapped market for me. After a week or two of posting on kindleboards and other forums, I finally got my first assignment. I was hired by author T.B. Crattie to remake the cover of his book "To Save The Realm", a cold war spy novel with just a dash of fantastical elements. It's definitely not perfect, and I had some trouble with the vehicle in particular, and I think I went overboard with the fog (the author specifically said that he liked how I made clouds and mist, so I figured I'd give him that!). Hopefully I'll get more projects coming in soon, and this will become another steady revenue stream for me.
