This seems right on the money. The maximalist texturing of the world constrasted with the doll-like skin surfaces is meant to evoke the specific feeling of a puppet diorama. The flatness of Zelda's nose is maybe the biggest giveaway. (although I think "rococo" is pronounced 'ruh·kow·kow')
Ah, that definitely helps explain the art direction. Skyward Sword and BotW were inspired by impressionism and Romanticism after all @sam-animeherald.northsky.social
