In 1974 (or there about) I did this drawing of a guy who I named "Neptonian". A lot of the inspiration for this character came from the Outer Space Men toy, Astro-Nautilus (with a bit of Star Trek the Animated series thrown in). I still remember drawing this and how much fun it was to do.
Seventeen years later I was still painting aliens. This one was done as a book cover for the James White novel the "Genocidal Healer" in 1991.
Astronomer • alien menagerie #4, was done eighteen years after "Genocidal Healer" (thirty-five years since the "Neptonian"). I'm still painting aliens.
*it's still a really enjoyable thing to be doing
