Great List. I would say that point 14 (practice) is the difference between a good and great presentation. I work daily with professionals helping them with their presentations visual communication through the use of PowerPoint Templates (http://slidemodel.com) and even with a great presentations deck, people may struggle to tell a story. And not because the deck is not appealing, or the speech is weak, but because the lack of rehearsal reduces the chances of the presenter to ignite the audience interest. My two cents for people that really want to excel at presentations is to create a rehearsal roadmap, make sure you are presenting regularly (twice a week). When an important presentation will come, you already have been exposed to the exercise and presentations will be much more enjoyable, for you and for your audience.
