Meh fair enough, if it's design it's design.
But nonetheless looks a little bit silly and out of place.
I didn't think it was supposed to look natural, because I agree with you in that it doesn't really look so.
But I thought it looked quarried, and therefore not out of place.
It's not illogical to build a factory in an old quarry.
I really love all these pictures.
I wish I had some of my own builds of high enough quality to justify taking such pictures.
