Great! Excellent! I like the angle on the nacelle struts, in particular. Nice, clean design. If the primary hull is the same scale as the
Constitution class - and I think it should be - then the secondary hull makes this is a little larger than a scout or destroyer. I'd say it's a light cruiser designed to carry an external cargo pod.
Good stuff! The deflector dish superstructure is a good design - far better than the simple naked dish that I've seen on a lot of other TOS designs that lack a secondary hull low enough to mount the dish on front of the secondary hull. The dish might block the planetary sensor on the bottom of the primary hull, but so what? You could put one somewhere else, y'know?
Great work.
