On the model: what Andy posted seems a bit true, now that I look at it. It isn't imperative, but it does seem that the first three decks are too rounded, and the impulse engine edges are too smooth. Changing the smoothing groups would work wonders here. Don't get me wrong: this is by far the best Sovereign mesh I have ever seen! Don't let anyone ever tell you less!
