From Fourthly Puzzled, I upgraded quite a few times, from the format to some new designs. The artstyle though I kept it somewhat consistent.
Human Yet Hybrid on the other hand, it changed not only from the format, but the story in the way. Back then my webcomics were long pieces of art with comic panels, up until when I got onto webtoon when I changed it to do them from page to page. And the very reason why I wanted to change it in the way my comics are today, so that I can still add some missing elements that were missing from the original episodes.
