Wow !!! I´m glad to see that Mr. McQuarrie is of good enough health to do a signing ! :thumbsup
I was really curious to see what concept design you´ll choose to produce, and it´s a real surprise to see the novel cover design come to life. Kudos to your 3D modeller, he captured it quite nicely. I personally would have interpreted the cheek and "jaw bone" areas differently, but as we´ve seen in the past, transforming concept designs into 3D objects is tricky, and the interpretations of what can be seen in a drawing can vary greatly.
I look forward to see more concept design stuff.
The HDSLA process is something that really has to be reckoned with, I guess.
