I have a minor suggestion for when you get down the road a piece with this:
One of the more interesting choices Nick Meyer made in ST6 was that the Klingons were the kind of guys who'd take bits and pieces of captured/destroyed enemy vessels and mount them on the exterior of the ship. It was essentially invisible in the film, but to be honest, I thought it made a lot of sense. Sort of like fighter pilots "keeping score" on the exterior of their aircraft -- only with a more Klingon feel to it.
Anyway, something to think about. It may not work with this design.
