Well it looks like I wasn't able to keep my nose clean. I've been notified by Newgrounds that my picture "Poor Peter" was removed. I was confused about the message at first since it started  reading as if I was in trouble for posting art that wasn't mine. So being the original artist I as like, "eh?"

Truth be told I think the fault is on me. My confusion with the rating system is partly at falt. From now on I'll just set all the appplied ratings too max with my pictures, just to be on the safe side. I rather be safe then sorry.

What also might have happened was the character perceived age. The lettter didn't say what I did exactly so I just want to cover my bases. Peter, the character in the main story is meant to be in his twenties, or at least thats how I've always seen it as I've written the stories. I think I might have aged him up as the stories got more intense. I'll make sure character ages are more clear moving forward. It's not like I blame anyone for the confusion, I can even admit myself that my past style makes it a little hard to tell.

Characters being underage is an element I don't have interest using in my art. That's not a shot at people who might be more relaxed about such thing, it's just isn't for me. I hope putting this here helps context my stuff a bit more. It's even one of the first rules specified below my commission rates.

I'll try reposting the picture again with proper context and ratings. Sorry to you all for my mistake. Thank you.
