They look like they were an enormous amount of very fiddly work. Very cool, though.

It's definitely weird, but I did enjoy reading it. I feel like it would make more sense if I read it again, but at the same time, I'm not sure I really enjoyed it enough to read it all again.

They get to ~8" long, so they're only as big as a very, very small bus.

I just finished the Powder Mage series by Brian McClellen. Entertaining books with an interesting setting and the outline of an interesting magic system, pretty quick read. Everyone does seem implausibly treacherous, however. You can definitely tell McClellen worked with Brian Sanderson, very similar style.

I also finished The Fifth Season, by N. K. Jemisin, which I enjoyed.
