Your favorite artist LOOKS like they make no mistakes. But the chances that they've perfectly drawn every line they intended to with a piece are pretty low. It's just that you don't SEE those mistakes when looking at the whole work.
Make that paper yours! If you misplace a mark, that's okay. Make it a part of the larger work and keep on creating!
