Scott Bakal has done an amazing cover for my forthcoming Tor.com story, "Am I Free to Go?" And he has a detailed post on the process of compostion on his blog, complete with preliminary sketches.
Not only is this a strong piece of graphic design that is impressive in its own right, but it also is a sophisticated reference to one of the more psychologically intense moments in the story. Just wait until you read it. Then you will understand quite how good this cover illustration is!
