How it's a site geared towards vertically-formatted comics BUT it also forces you to chop your comic up into ten million little pieces. My first time uploading a comic on Webtoon was not pleasant, to say the least. I had no idea what I was in for...
Also, I hate how everything has to be jpegs. Even the comic thumbnail has to be a jpeg; it's ridiculous. I can understand a file size restriction, but a format restriction just feels too...restrictive.
I'm not your average webcomic artist, in that my image dpi is like...100. ^^; It gives me a "distinctive style", sure, but it also means that the pages start looking wonky if you modify them in any way.
And if you turn them into jpegs they look like TRASH. It's like watching a cheap camera recording of a movie; I'm almost ashamed to have them up there. But there's not much I can do about it...
