Quite like that look myself,deflector array further back works for the Aventine, speaking of Voyager..I would think some MVAM nacelles would go nicely on that(along with impulse engines in the nacelle struts), actually ...lol, would think it would be a good counterpart for the Aventine in the same texture scheme.
Though after looking at it some more...wonder if a shuttle bay could do with being further up the back towards the saucer section(sort of how the impulse engines are on DJ's Eclipse class) and more of sloping back end on top of the aft section
