I mean, it wouldn't have bothered me as much if you hadn't like...Onelined with them. I mean, if you are going to have some exception and have all 4 characters you should at least be making the extra effort of using them. Having that many characters means that you should be going the extra mile to bring out their personalities, their thoughts, and describing their actions in detail. Should be able to post with the same level of descriptive detail with one character for each of those characters, it's a lot more work. That was like your moment to demonstrate that you could handle 4 characters and it wasn't even a post that equated to a single paragraph collectively. If anything, that post shows that 4 characters is probably too much for you at the get-go.
Multiple characters isn't for everyone.
Especially if you can't post at least at a casual level of 2-3 sentences per character.
