Re: NX class ship - what would you change?
I'd do away with the conveniently heavily-shielded walkway in the nacelles. Include science labs (it is an exploratory craft after all).
Externally I'd have a separate drive section (where the deflector dish would be located), thus making the front of the saucer round.
