This is the best version of this early concept of starship Enterprise I have ever seen or imagined. What gave you the idea of the star core in the heart of the drive assembly? That looks just sensational!!
Years ago I did a basic sketch of an unrelated ship that just sort of happened to look a little like the ringship, with a "star" in the center. I saw some recent pics of other people's ringships, and remembered my old drawing, and decided to have a try.
