Sorry, I commented on this post and saw then it's two years old. But, I thought I'd throw a comment in here too.
Rules are there to be broken and learning and going by the rules is how you know how to break them properly and for a reason. Rather than doing it by accident. I guess it's the difference between being an amature or proffesional. To a certain extent.
For example, in film there is something called the 180° rule, it's common and most people have heard of it. In camera set up your camera should stay to one side of the actors, to follow their eyelines. As it allows everyone to know that character A is to the left of screen and character B is on the right. The rule is broken if you flip the camera to the other side of the actors. Amature mistake, unless there's a reason.
Like for example a characrer changing there mind, or learning something that sickens them. It's known to disorientate an audiance. So there has to be significance for doing it.
