Ok, i made three more changes...two I like, one I dont.
First, the wider trench moving back to make the plasma vent wider works for me. It looks good, and doesnt take away from my original "in trench" idea. Second, the longer front is ok....not wild about it, but it still works.
I have to say I dont like the trenches on the side of the nacelles though. I think it breaks up the overall "pod" feeling of the nacelle. My intent was threefold with the nacelles...I wanted an ovoid shape to carry a galaxy cue, a minimized bussard to give cues to the intrepid, and the overall one piece design of the Sov nacelles...getting away from the head trench that the Intrepid and the Galaxy had. The trench doesnt work in my opinion, but Ill leave it up to you guys.
