You, sir, are a legend. I've had Atomic Rockets bookmarked for many a year, and my work has been greatly influenced by it. Thank you for opening my eyes to the beauty of realism...
... even if I do suck at math >_>
Robert Heinlein is a bit of jerk since during WWII early 1940s Robert Heinlein advocated genocide and at a Hugo or Nebula Awards writer Jeanette Ng has commentary about politically correct villainy of early 1940s WWII .
Jerry Pournelle is a much better writer since as a NASA engineer he has published bold optimism of "Endless Frontier" .
Did you ever read anything by Caldwell and Cowley or art books by Paper Tiger Ltd. since when I was kid comic books were considered uncouth in the shadow of Fedric Wertham?
Still "Jack Kirby" machinery is detailed as are some Manga and Manwha comics worth a read.
Jack Kirby Interview makes claims about Nikola Tesla's involvement during the early 1940s Manhattan Project.
I am impressed by your illustrations of the "Traveller" series "Scout Courier".
Do you do commissioned illustrations and if so could you please list a physical mailing address or a phone number of where to contact?
