I think we should blame Aunoma for the horrible decision of going cel-shade. DAMN YOU!
Has anyone heard that story? Apparently Aunoma had been sketching things while making Majora's Mask, and came up with the Cel-shade idea. After they finished it, and when Shiggy was working full force on the realistic Zelda, Aunoma proposed the idea, and Shiggy turned it down.
Then, some how, some way, Miyamoto changed his decision. And that's when it went wacky.
But still, I love the new style.
