My only pet peeve would be the impulse engines being simply slapped on there. Something unique could work though... Other than that, I really like the design, it looks more like an upgrade/variant of the Ulysses-class Dreadnought, following that design lineage rather than more of your standard "cookie cutter" Dreadnoughts that are simple kitbashes of the Constitution-class. I don't mind the V-neck though as opposed to some others, as it looks like it better supports the saucer, much like the case with the saucer section of the Ulysses-class. The only other alternative would be more of a slightly primitive/older-looking take at a thicker neck that resembles (but isn't as thick as) an Excelsior-class's neck, but again, I like the V-neck and would support sticking with it when the case comes.
Fantastic work Dizzy. But considering I only have SFC1 installed at the moment (I can install SFC: OP soon), I might not use it anytime soon, but I will get it, definately, for when I reinstall SFC: OP. Of course, assuming that this won't be available for SFC1.
