Just checked on Tor.com and they are posting a link to this chaps concept art which is extremely good. The guys made one post + a post to thank the well wishers and gets on Tors front page in one shot. Its very good stuff. I like Syd Mead and collect what I can of his stuff but this might be even better... maybe.
