I just want to say something.
Art thieves are gross. I mean, why would you do that? It will eventually be found out that the art isn't yours, and it will be thrown back in your face, because some people aren't very nice when they confront you. Eventually, the original artist may confront you, which happened recently, I know, and the person was just like "This my art, how dare you." To the ORIGINAL ARTIST. Please no. Because I will say one thing, no one is impressed when you are an art thief. However, even if your art isn't amazing, people will be impressed with that, because it is you. Your drawing represents your own amazingness and skill, and that is impressive. So yeah.
Also, to make sure your art isn't stolen, sign your art. Then, you can confront art thieves and say like "Do 'your' signature on a random piece of paper without any art attached and send it to me, and I'll do the same." Then, they can't deny you. Also, if you sign with your name or username, that will make sure your art isn't stolen.
So, moral of the story, don't be a gross art thief, and sign your art just in case. (Honestly though everyone has a unique style, so it shouldn't be that hard to confront an art thief if it happens to you)
So yeah.
