Thinking About Story Boarding...

Now it appears I have my concrete idea, I need to start thinking about story boarding and getting my idea on paper. One of my main concerns is that it wont have enough content to fill 4-5 minutes. I think the best way to do this is creating a very intricate story board and filming it so that I know how long the shots are going to be etc.
When researching Laurent Bourdoiseau I came accross a colaberation of different things he's directed and how his production team  story boarded it.

This gives who ever is working on the actual filming a very good insight into what actually needs to be done. Obviously my drawings wont be as good, or probably as detailed, however I can attempt to do a similar thing. I think it will help to move the process along. Then at least I will know how long it will take, hopefully. Which will mean even this early on in the process I can gauge how much content I will, and how much filming time i'll have to ensure I have.
