5) Eye line.
By that I don’t mean heavy eyeliner like Charlie Chaplin used to wear. I mean make sure you’re looking in to the camera. There’s nothing worse than a presenter looking down at his shoes or up at the ceiling. If you start glancing over to the left or right the viewer will get distracted too.

6) Stance.
Try not to stand straight on when talking to the camera it looks like you’re about to have a police mug shot taken. (Probably after the bank job) Stand at a 45 degree angle with your front foot pointing towards the camera. Then turn your head towards the camera not forgetting your eye line.
