Some years ago I tried to kitbash a TNG refit Miranda, but I soon ran into a problem, the parts I wanted just didn't exist!!!
Anyway, things have changed. I can model from scratch now, more or less.
Anyway, here's the prelim of where my new model stands now. Not much is different at this point, except the saucer is slightly changed. The underside doesn't have the same concave curve as TMP Mirandas have, and for good reason. As the ship progresses, the differences between this ship and TMP Mirandas will become more evident.
