Video Pitch Feedback

I presented my pitch the class and got feedback. Most of feedback was asking about the locations. "Do you the location, especially the field?" I have found a field I want to shoot my music video in which is a public field so we don't have to worry about permission.
I also got told that my idea of the music video is similar to the original music video. My music video will have a story line instead of Taylor Swift's which is just random home footage of her and her family and friends.
 I got questioned about how I would film in a super market. I already have permission to film in a supermarket so that won't be a problem.
