The design is very nice, the nacelles flow and have a post-TNG era look to them. Very advanced, very symetrical, and not too busy. The saucer section looks similar to the 1701 refit, especially the lower section...while the upper saucer incorporates what I assume to be either fighter/shuttle bays or some sort of deflector dish. From the top down, the design looks alot like a miranda class, except that the nacelles are above the engineering and saucer sections rather than below.
The structural supports that connect the nacelles with the saucer and engineering section are also very attractivly designed and the curved look is much more appealing than the straight across "roll bar" look that the miranda has.
From the bottom up, it looks like the engineering section of a Oberth class, and we see the only part of the model that I don't like much. The main deflector dish doesn't look "right" IMHO. Of course, that design might be due to some model requirment that I'm not aware of but it doesn't really have the flowing design of the TNG era, or the simplistic look of the 1701 refit. I think it comes down to the smaller circular model that's sticking out from the main hull. But that's just a minor quibble, and I think it's just a matter of taste.
Overall, I think the model shows quite a bit of thought, very apealing design aspects while not being too busy.
Very well done.
