I'm Planning On Creating A Cinematic Film And I Need Help

So I'm trying to create a film to get back the one who got away and I would appreciate any advice. I plan on filming at a carnival and having it sorta dramatic while giving off a feel of emotions. I do plan on shooting slow motion shots and also having the audio cut out for the added effect. I'm still trying to find the perfect song for this film. The carnival that I will be attending is in 3 days so any help ASAP would be appreciated. Thanks for your time and I'm hoping that this project will be a success.
