Yeah I should probably put that on the rules page. It's just that when you post two things that are so similar in the gallery, you almost get an unfair advantage over the other art in there because the two are side by side and gain the attention of viewers. I also just don't like everyone posting duplicates of everything and cluttering up the gallery. Don't take it the wrong way though. I'm not saying your art is "clutter."
Personally I like this version better :-3
