I know I may be a LITTLE off topic with this post, so you can be mad at me all you want, and I'll delete this comment if you want me too.
But many inexperienced artists trace screenshots, or copy poses, all the time for their FANART galleries, and either make it the same character or a different character. And almost no one thinks that's wrong. (not posting my opinion on wether this is wrong or not)
So aren't renders basically the same thing? It's just a thought.
