No, this is not specifically about waifus and their jiggle physics or whether the newer character designs are better or not. We will focus on the fact that each character in Teyvat not only has their own personality or something that makes them unique. Although all the 3D models seem to be the same, Genshin Impact characters have certain changes, which is more noticeable in the Vision Bearers from Natlan. This went unnoticed by almost everyone, but one player looked into the details to discover these subtle differences.
Redditor khoast40_KH40 shared his finding on the subreddit r/Genshin_Impact, but that wasn’t all. This user made several images comparing the characters according to their model type: Tall Men, Tall Women, Medium Men, Medium Woman, and Loli. In most cases, except for the Medium Men image, the Genshin Impact characters models have height changes, and the tallest ones are the Natlan ones. Not only are the characters taller, but this difference makes them have fewer bobblehead-like, well, heads. Also, before, the community believed that all playable characters used the same base model, but in reality, there is more variety than is apparent.
On the other hand, in the Medium Men picture, Kinich is not the tallest and also follows the average height of the other characters in his category. Xiao and Wanderer may not appear because they are known to be among the shortest guys in the whole game. However, for the Medium Men, surprisingly, even though Kinich is not taller, his face is less elongated, another characteristic that makes him look less like a boy. I wish there were more variations of body types and models like in Zenless Zone Zero or Honkai Star Rail, but at least little by little, they have more variations now, and perhaps in the future, there will be even more.
