Hi, Dennis, IDK really if selling on Webtoon is the best idea. At least, once you decide to do it, I'd consider possibility not to limit myseld with the sole marketplace, but to try promoting the cartoons at several resources. To deversify risks, to expand the audience and to see what would be the effectiveness of each. Also, it depends on the style, genre, etc... For example , you can check out this review (https://tms-outsource.com/blog/posts/apps-like-webtoon/) and try other alternatives. IMO: it would worth to go far and to make a books of comics or, even better, to make them animated and get the added value. Anyway, it's up to you.

Hey, I don't think that this is necessarily the best place to ask. We (as a community) mostly focus on the technical aspects of drawing and painting -- Color, shape design, anatomy, etc. However, I think I found a site from Webtoon themselves that could help you out! https://www.webtoons.com/en/creators101/webtoon-canvas Proko also sells a course on drawing traditional comics, which, while not necessarily the same, certainly overlaps with the Webtoon format.
