Two variations here... One with the two hulls separate and connected by a neck, and one with the two hulls connected, but with a clear break between them. Any comments? Preferences?
I like both, but probably the first image more (but with a beefed up neck to prevent it from accidental - re: Klingon intervention - separation from the rest of the ship).
The only thing that jumped out at me was the placement of the deflector dish. You may want to raise it a smidge. At its current placement, it will tear the bridge and parts of B and C decks off when activated.
Just a thought. Great work on this.
