What are some good examples of the art getting worse overtime..?

I was reading a manga and noticed how distorted the characters looked so I reread the first chapter. The characters looked SO much better. It was the same artist. The MC went from a nice looking guy to an oddly shaped femboy creature. It got to the point where someone commented “he is literally just a woman atp”
Inhuman big eyes, huge lips, and a weird top heavy haircut too. He became a skinwalker.
