Only one suggestion comes to mind:
In the forward view you posted, the stardrive looks a bit "droopy". Any chance of making it more rounded underneath? And possibly make the aft edges of the saucer a bit more rounded as well?
Loving the design thus far. By my count, you've got atleast 18 phasers in its combined mode together with 8 torpedo tubes. Perhaps this ship was built for a renewed conflict with either the Dominion, or dare I say it... The Klingons? (STO reference)
