This looks like a play setup to me?
It has some great ideas, but it's too colourful in my opinion.
I recommend that, since you obviously have a sparse amount of bricks, you cut down the size of the MOC to be just one thing. The courtyard where they rookies train, the reception and so on.
This is too many things with too few bricks and it looks more like a fantasy frame for playing.
Plus the whole thing is so dusty it's hideous
