I agree with what Cordanilus said about the saucer (at least the image, not the complete new one).
It does have a heard angle, but that's what Dalekanium's has, he just needs to make the section that pops out larger.
I also agree with Cordanilus's statement about the nacelle strut. I needs to be a bit thinner to give it a better flow with the rest of the ship.
I do like the curvature of the nacelle though, please don't straighten it, if it's too straight, it doesn't seem right with how curvaceous the rest of the ship is.

I'd just like to mention, this is just my two cents. It's your project, do whatever you want, as long as it's available for download eventually, I'm happy.

Also, I attached an image of where the nacelles seem to be (or at least where they seem to be, to me, in the trailer)
