As for other images of cast members, I found these images of the USS Titan
's crew on deviant.art - here
- and I always go back to Geoffrey Thorne's thread (TTN: Sword of Damocles
author) and his cartoon-style drawings here
. Some of them are not entirely how I envisaged them, but it's a good place to start.
Thank You, for those links. I really enjoyed all the Titan pics as that is my favorite series.
