I like it thus far, would rather see some weathering. While it is true that anything in a vacuum would be perserved, space itself is not a true vacuum, nor is it a closed system. You have many sources that make space a very extreme enviroment to build in, not to mention an enviroment that would degrade the exterior of any ship. Plus if its klinker, its a warship most likely. I would expect to see some scaring on the hull.
Besides weathering, I would work on making the 'brick' work blend a bit better. this could be accomplished by fading them and then making them part of larger panel work.
