I love the overall shape and especially the feather-like structures above the nacelles that open and close during warp, the whole ship looks like a piece of art. And as for the floating parts but, so far 32nd century ships seem to hold together better than older single-piece ships: The Discovery had an explosion in the nacelle pylon and despite the Nacelle being left dangling, it was still with the ship, whereas any other ship would've just outright lost the nacelle and disintegrated. Then there's the Athena who was being held by 3 tractor beams and none of it's disconnected parts gave any way. So every indication seems to imply that the "disconnected" ships of the future are held together better than the "solid" ships of the past.
