It looks almost like a step backwards in some ways
I'm sure this is a controversial opinion here, but my wants and desires for Zelda artstyle has kinda changed. Don't get me wrong, I love the way Botw looks, really good blend of cell shading and a more grounded style. But I feel like this style has been developing since Skyward Sword, I know SS isn't exactly the same but it is pretty similar. Anyway, I think that because by the time the next game comes out, it will have probably been upwards of 15 years of Zelda going for this similar style, I just want them to try something different. I like the novelty of Zelda games' art changing, it just keeps things exciting. I won't lie, with Tears of the Kingdom I was becoming tired of the style because it's been in my head space literally since 2015 or whenever they revealed Zelda Wii U, and I was especially tired of the world by the end (though that's a different conversation).
I used to be a person that was staunchly against the idea of the team going for more of a realistic style, but honestly, I've come around to that. I used to have the really dumb idea that "realistic style" means that there is no stylization at all. I've played games like Dark Souls, and while that's going on a 13 year old game or so, I still think its world aged really well. Just because there are a lot of dark colors and dirty textures, doesn't mean the art has no merit. The enemy designs and environmental designs are some of the best I've seen anywhere, I mean you've got a dank swamp, a lake of ash, a beautiful high class golden city, a spooky looking garden, cool castles. And to top that all off, the style really compliments the story and what's happening.
Now I'm not saying the next Zelda art style should rip off Dark Souls, but I am saying, that going for realism CAN work. Combine that with the idea that the next system should have pretty beefy hardware, and I would just love to see them try a rendition of that style again since it's been so long. I'd also like something a little different than the "ruined naturalistic ruins" type of thing, it's just been every where since Botw released.
