Amazing work. Interestingly enough, I rather wish they'd gone with this design for the E-D. I've always thought that (intentionally or otherwise) the E-D shared many of the same general lines as this ship. Unfortunately, the E-D wound up with a big, duck-billed primary hull that kind of makes the design less attractive, IMHO.
This design, with the circular rather than ellipse-shaped primary hull looks much nicer.
Who knows ... 30 years from now when it occurs to someone to reboot TNG a la TOS, perhaps a design like this will find a place.
I definitely like the telescoping radar dish, but I'd probably place it directly behind the bridge rather than off to one side. Something about symmetry in starships feels sleeker to me.
