This is a star trek tribute: a mix between the star trek style ans the classic LEGO® space style. LSS Bonaventure has a large bridge in the saucer, and multiples openings in the main hull as shown. It was hard to find a way to clip nacels. Some previous versions of the Bonaventure had a longer neck between the hull and the saucer, but is used to fall very often, that's why I shortered the neck. I added the 3 first photos, it's the Bonaventure-refit.
