Nad did a good job in her intro and having teachers and friends make comments about her.
Erin had a creative effect that captured people's attention but the first 30 seconds of background info (school, year, live) is not needed; those things have and will change. Focus on the future of what you want.
EJ was creative in using writing to express her message, which especially worked since she is a writer. Her content could have been developed more.
Francis did a great job in dressing up and going to the streets although the audio is not the best at times and needs better content to convince to hire him.
