That looks like you might expect a Freeport to.
It's not overly reminiscent of Freelancer, but perhaps that's what was being aimed for.
The form fits the function, I should think - except for the fact that I don't really see any mooring points for large vessels. Freeport 11 gets a LOT of large vessels.
Maybe you could make four more arms, sticking out between the existing four. You could make them similar to mooring fixtures, just larger and better and more station-like.
