One of my favourite reference guides in my digital storytelling library is a book by Sherri Sheridan: Developing Digital Short Films.
The book is divided into 4 parts with part 1 devoted to Digital Storytelling. This section is packed with ideas, quotes, graphics, charts, notes, and suggestions.
Here are a couple of quotes from page 18:

"It's a great responsibility to be a filmmaker....
Page 36 speaks to how people often choose films based on what type of emotional ride or world they are craving to experience. The author calls this segment: "Story Flavors: 37 Varieties" - - Many topics are defined including historical, personal, societal, biographical.
So, I recommend this book to you. Perhaps your local library has a copy. Well worth reading.
