People Within the Music Video

As I'm not fully sure how many people will be mainly filmed within the music video as the song could be suitable for even only one person as long as it's filmed effectively and has a great look to it, However my main aim is to have two or three people, All having their own look to add to the music video as well as the main look I am wanting for the lead singer. However I will be planning out the whole storyboard and seeing which would look best and where, also where it could be suitable to have more then one main performer.
