I love it so far, the only thing I see ( idk if you've noticed) that may help you is if you finished the exterior first. on the bottom there is a bit of reactors hanging out and also a few issues with the turrets. I feel though (because it looks like your doing both exterior and interior at once) it will be easier to build inside and know how much room you have if you finish the exterior first. (remember I'm not trying to be rude, just trying to help a bit) but keep up the great work and I cant wait to see the final result of it. and also if you are building this alone, I wish you the best because it is very difficult to do something like this solo.
