I feel that the speech that you chose was very unique. Robin Williams was such an amazing person and he truly connects with the audience every single time he speaks. I agree on how important it is for a speaker to maintain eye contact at all times to demonstrate respect and that he put effort at learning the words and at the same time being extemporaneous. Confidence is also a very important factor and Williams showed it throughout the whole speech. You did a wonderful job, just remember to include the main points and how he managed to pass from one point to another. Good
