Absolutely awesome! :)

So much great concept art goes into movies (and games) that we never get to see.

This one (http://www.ryanchurch.com/images/tf2/images/ARKnemesisCOCKPIT3b.jpg) really makes The Fallen in his chair on the spaceship even more like the Emperor in Return of the Jedi!

I'm surprised how close to the concept art the movie got.
