I'm going to draw a comic in English, not my mothertongue but I want everyone in the world can read it. I’m not a professional, not to mention that I’m a total newbie in this field. I’m inspired by the webtoon Tower of God.

Hi! I think it's really cool that you intend to create a comic! I don't really know a lot about comics and publishing, but maybe the wikipedia page fives you a good idea regarding the possible formats.
