If the tower supposed to be on top of the ball aka DS then the lines that describe th surface are all wrong.
how about the lines gathering into one point and show the indication of DS's axis and center?

Very rough. ignore the hole just see the line position/direction

Actually, if the tower is to be at the top of the DS2, I think I would prefer that appearance, with the tower coming out of a depression or hole like that. I could see guns on top of all of the "buildings" as a means of protecting the tower, as well as the much larger exhaust port (being that this would roughly be the same location as the exhaust port used to to destroy DS1).
This would almost be fitting in a way, in that it would almost be like a dare for anyone to try the same trick again, as well as showing that the Emperor at least thought THIS one out (hmm, if we build another one, we gotta do something about that exhaust port... hey, I know! I can plop my butt right on top of it! And surround it with lots of guns! NO ONE will be able to defeat me now! Wait a minute, I have someone on call waiting...)
