While the designs aren't for me, I feel like we need to see a few more to get a feel for what's ahead. I think the other regions are remarkably consistent and cohesive.
Jean, Amber, Kaya, Lisa, Venti - they just look right. Same with the likes of Diluc and Eula.
Ganyu, Xiao, Zhongli and Hu Tao are similar. Yelan, feels like a slightly different branch of that character design ethos, but still cut from similar cloth.
Kaz, Ayaka, Yoimiya and Raiden (and loads more) - for me Inazuma has the most consistent look. Thoma, Sara and Sayu all fit in really well too.
These characters as a collective feel a bit scattershot, so intrigued to what the overriding character design flourish will be with this region.
