So uh, suppose I have an idea to draw something, and in the midst of working on it, someone else had just done a piece with the exact same concept, but executed better. Do I wait for a while before posting so it doesn't look like I immediately copied it? Do I give a disclaimer that I came up with it independently from the other one (I'm kinda afraid no one would buy this)? Or do I just pretend to not be aware of the other art at all?

I think I'm gonna go with the last option unless someone has a better idea.
