Listen, maggots. (and I mean that in the most loving way posible).
About Hetalia OCs...
You should do your research on them, or there's no doubt that you're going to get targeted by the people who hate shitty OCs. Don't make them a Mary-Sue or Gary-Stu. You also might offend someone who's from that particular country.
There's a flip side to the situation.
People who go around "critiquing" OCs...
You better be sure as hell that your 'critique' is actually helpful. Because critiques can hurt. And they do. (Well, some of them).
Completely slandering someone's inaccurate OC? That doesn't help. At all. Calling it a "piece of shit"?
You can be pretty damn sure that the OC creator is going to bitch at you for that. I would too.
Actually, I would probably just mock them, but still.
Instead, you should politely point out that their OC has some flaws. Also, pointing them to sources with information on the country is always nice too.
Critique =/= Trolling
Critique =/= Being a complete dickhead who isn't actually doing anything to help
kthnxbai Actually nobody has ever attacked my Hetalia OC , but this is coming from something that recently happened.
