Oh well.
Are you going to keep that very broad lower sensor dome?
I liked the spare lines you had before you added the more elaborate bridge.
In terms of the lower saucer, I remember a bronze looking ENT-D study model with a feed horn in the deflector/sensor dish area, and a very broad, undetailed lower saucer--as if there were this huge passive detector there...
Honestly I'd like to rethink the whole structure atop the saucer. It's okay, but it really doesn't seem to go with the rest of the design. The only part I really like about the current setup was enlargening the trubolift nub into the upper sensor array with the lozenge shaped dome. I want something that looks good not only in profile view, but from different angles as well.
I'm trying to think of something different than the usual sensor dome. I actually considered putting a ring of light near the base of the saucer. I'll think of something.
The devil really is in the details. I, too, find myself resisting/rethinking choices made almost by reflex. Trek ships have been designed a certain way for so long that it's a challenge to look at it differently even as you want to keep something of the familiar in the exercise. Even the hangar area I kept now has me thinking about how to do it just a little bit differntly while still keeping that half dome shape at the end.
