There is one thing I definitely agree with, the newest FED designs aren't fluid at all, they're blocky industrial looking vessels.
The Odyssey was fluid, it's one of the nicest FED ships in the game.
Some of the linked said 'JJ Trek versions' also seem nice, but I'm reluctant to call them 'JJ Trek versions' because his Constitution is ugly as hell (and the worst thing on it, nacelles, is also the least pleasant part on those other inspired designs).

I think Cryptics designers often overdo their Designs, instead of keeping them simple.
What i wish, to have are more different but basic ship parts.
No fancy Saucers, Pylons, Nacelles or Engineering Hulls, just some simple basic shapes but much more variations for us to use.
For example, they did it right at the the various pylons of the Star Cruiser variants.
Some are facing forward/ backwards, some are upside the ships center, some are lower.
The same with the Heavy crusiers saucers, some round, some streched.
THATS what i wish for all ships. More Variation instead of focussing on little details, no one sees from a distance, i do much more care about the general shape of a ship.
This is one of the contest entrys for the new Enterprise (which was won by the Odyssey ) that called my attention.
I think that's a excellent example of how to do it. It preserves the basic elements of a Starfleet ship and gives it really gracious lines.
Apart from the realy fragile looking pylons (which are also too extended IMO) the ship is exactly what i am looking for. Even the nacelles look really cool (which isn't easy done, most of the ships have somehow cheap looking ones) althrough they could be too long (again), but thats not easy to see a this angle.
What i also like about that design is the much stronger looking neck, which always looked too breakable on the original constitution and the refit. But here it is done in such a good way, it blends perfectly into the general shape of the ship.
