Could one of those be the Goodson class? http://www.neutralzone.de/database/Federation/Other/_GoodsonClass_NCC-7105.gifOff hand, I don't think I've seen one I liked so much it became a favorite. I've seen, off hand, a couple I liked.
I can't recall what it looks like now, but I remember seeign a scetch for a large Federation ship (the U.S.S. Titan?) that was going to be Riker's ship, that was going to get destroyed in the Borg battle in the opening of First Contact.
There was also a ship, I think I saw it in a Trek book with concept art, that kind of looked liek it was from the Excelsior class period, had Enterprise E-like nacelles, and at the front of the saucer (it was a top angle view of the ship) it was indented like a box, only the sideswere pointed outward at angles.
I was flipping through the Sketch Book for the first two TNG films and I saw a small sketch idea for the Enterprise E that had an itneresting design idea: flat angled out fans nacelles. Reminds me of something I did with a ship I built.
It also reminds me: every single sketch for the Enterprise E, was ugly. All of them. The shi pwas doomed from the beginning. Then the artist(?) commented on get an approval on the ideas or a pass. As I recall, it was once again Berman's fault. This guy couldn't stop himself.
