I'm actually sad that some things are a bit "blury" and some doesn't really make much sense in Squares modeling.
I mean, in nmkin_5 there's ladders and balconies going from nowhere to nowhere. I started to try to figure out something to give them sense, like it having 3 different floors but then due to the reactor "hole" it brings that theory down. Then i thought "Hey, maybe the reactor is just a cilinder and that black shadow is really the reactor just not enough lightning to see it all", and well, it would look good, that yellowish texture just behind the reactor would be a second flood, with a fence around it and with those stairs actually going from somewhere to a third floor where you could check the top of the reactor. But somehow, i find that the curve on the top of the reactor just doesn't compute with this logical theory.
Other than that it just looks confusing with stairs going from places you can reach to places you can't reach either, some grids that also dont make sense since it wont improve the building stability, etc.
Just my point of view tho.
