Just a generic Zora?! Mind your words! This is the one and only Laflat, from the Lynel quest. The by most cutest Zora in the game.
There is nothing design-wise that separates Laflat from other female BotW Zora other than the book she carries, which is absent in this picture. Compare Zelda wiki pictures of Laflat to other female Zora such as Tona and Marot and you will find they are identical.
The commentary from the source tweet reads "BotWゾーラちゃん" which translates simply to BotW Zora-chan. While Laflat is indeed a cutie, there's no indication this is her specifically. Removing her tag.
