This is not a very clear question. The word "unnatural" could refer to too many different things, so there's no way to be sure what you are trying to find out exactly. Your writing could be unnatural for many reasons, ranging from something simple like your hands being cold and causing you to write unnaturally - all the way up to brain damage that causes you not to be able to write.
