>>7189711Same anon here: you might also want to see if any of Megan Rothrock's books are of interest, because she was a former set designer. She has a series called The LEGO Adventure Book, with volumes like "Cars, Castles, Dinosaurs, and More", and "Robots, Planes, Cities, and More." I haven't actually flipped through these books, but my library has some and I plan to get around to them. The books feature a lot of example models (picrel) for different ideas and somewhere between 20-40 step-by-step breakdowns. But I've never cracked their spines and can't comment further, but figured I'd bring it to your attention.
This (
