My personal limit is under 2K per chapter, but on this app, I think around 1K is best.
I understand it’s a comic book site, but I don’t like pictures inside the text, before or after, and small size is okay
Each speaker starts new paragraph, but I am fine when there is a description between two lines of dialogue from the same character in the same paragraph.
Dialogue attribution with simple words OR replaced with a decent description. I prefer not seeing a ‘said, while doing’ or ‘verb+adverb’ often.
Paragraphs that are 3 to 6 sentences long, so it doesn’t look like a packet of spaghetti, but also doesn’t stretch too long.
A balance of description and dialogue.
Since italics are a PITA on this site, I don’t care if there is no italics for thoughts, because people can’t be forced to re-edit every chapter
