While there's no telling how close that is until more images are released, I think that's at least a good 1.0 for ya Wiley. Good job.

EDIT: One quick thing, you might make the nacelle pylon curve back a little more as it attaches to the engineering hull. Sweep it back flush with the edge of the shuttlebay, like on the schematic. Also, it may just be me, but the bussard assembly seems off, but I can't tell for sure. For the most part, it matches up what we've seen.
