I just bought Dave Dorman's art book off ebay from the man himself, which will include a detailed drawing above con sketch from a character of my choosing.
Haven't decided on the charcter though. I've already got a head sketch of the rocketeer from dave so that's out. I've got the prelim to one of his Crimson Empire covers so Kir Kanos is out too.
My shortlist is, Han in Hoth outfit holding luke's lightsaber, Indy, Count Dooku and Nightwing(modern costume.)
