It's nice to see a person with comparatively little posts doing so much for the community.

Your modeling quality sure is top notch, with elegant curves and few smoothing errors. Regarding this design in particular, I like and/or love pretty much all of it. The loves are the overall shape, the nacelles, the Vesta-class-like bridge area, the Argonaut-class-like upper saucer, and the new, more traditional deflector.

There are a couple areas that I think could do with a bit of improvement though, namely the impulse engines and the bussard collectors. With the impulse engines, I'd suggest you differentiate the fore and aft set a bit. They look very much copy/pasted. Also, the holes look sort of simply drilled into the bulges, kind of like Flash Gordon-sytle sci-fi. Lastly, regarding the bussard collectors, I think that in the top view they look too pointy. Perhaps broaden them out a little.
I attached a sketch that includes a couple of ideas regarding the impulse engines and the bussards. Personally, I think you could extend the Vesta class influence to the impulse engines, both fore and aft.
