I've been trying some different story-boarding styles, from keeping it black and white to stylising it with bright colours, but I'm settling for a style which I feel will be capable of progress as well as matching the mood and setting of my story.
A style which I would like to mimic or at least borrow from is the Comic series of Tintin. Created by the Belgian Georges Remi it was a series of comics, books and eventually TV films about 'TinTin', a young reporter and his dog Snowy. I forgot this existed until I was researching storyboarding and came across it. I really like the simplistic style as it still shows emotion and action.
