Interesting idea - presumably, something like an aircraft carrier, but in space? [EDIT: Clearly, I didn't read the OP thoroughly, huh?
)
One nit and one suggestion: I've never liked the deflector dishes hanging down on stalks - it always looks flimsy and prone to damage just from use. To my mind, the deflector needs to have some real support, because it's projecting a force field, and one would think that even then, Newton's laws should have
some application - any force projected forward should have an equal and opposite force in reverse, pushing against the deflector itself. Mounted solidly on the bow of the ship, the mass of the ship backs it up, but those stalks -
SNAP!!. And in this case. it seems doubly unnecessary because the ship does have structure immediately behind the deflector, so why not extend that structure forward and incorporate the deflector?
As for the bridge, why not reverse standard practice and sling it
under the ship? Not the whole double dome like we see on
Enterprise, but the smaller dome that contains the bridge itself would be upside down, maybe at the centerline of the forward curve of the hull (just for aesthetics).
Just as an aside, you might want to drop the engines downward, so they have clear space between them, rather than sweeping them unnecessarily upward without actually clearing the hull. That's long been a trend among Starfleet ships, that the space between the nacelles is clear (though, obviously, not a hard-and-fast rule).
It also needs some detail on the upper hull - maybe traffic control pods that have a view of the approach to the open hangar.
Just some thoughts ...
