Let me ask you a few questions.
-Do you want to write a book?
-Have you ever wondered how to get started writing it?
-Do you have a head full of ideas and scenes, but no idea on how to put them together?
Then this youtube tutorial may help. It’s over the concept of Storyboarding. It’s worth a watch.
It’ll give you a great overview on how storyboarding is done and how to plot your book using the three act structure.
After watching it I think you’ll find that it’s easier to figure out where the scenes need to be placed in your overall plot.
