Both of these are my favorite art movements, so apparently I'm playing for both teams.
An important distinction is this is Machine Age Art Deco. Earlier Art Deco was more like tidier Art Nouveau.
supposedly the latter is more specifically called streamline moderne
This is a fantastic perspective I hadn't considered
I don't really know much about art but aren't dwarves more like brutalism?
Dwarves still have decoration, both in their craft and in their style. Braids, carving, etc. Brutalism does not have the intricate design dwarves seem to. It’s all big and blocky.
It depends a lot on your setting, obviously, but dwarves are specifically known for going above and beyond on craftsmanship.
