I audition alot of Ad Agencies and have had many diverse pitches. First if he was talking to a client I would think he was incompetent. If I was a colleague I would think the body language gave off an impression to disingenous self honesty.
Way to much movement in his articulation of thought and animation. Verbage to imagery of thought does not sell true mastery of illusion that is the heart of the Ad game in his video.
