Don't worry Sisqo - i'm sure your writing is really good. You're just at that stage in the year where you're picking out any negetives in your answers. However, if you feel like you are telling the story too much, just use less examples and elaborate on them. For example, if you've given an example that shows how Lighting is used to develop a character, focus on the directors intentions in doing this, and then follow on with how it is suggested to make the viewer feel - You are probably already doing this (actually i highly doubt you wouldn't be because you know your stuff), but just relax when you are writing and prepare a thorough plan beforehand.
That probably doesn't help, but i'm sure you're fine anyway!
