I do not know of any books explaining how to do anime storyboards, but there are lots explaining How to Draw Manga…
the real comics, I mean.
Can you already draw manga characters, or are you an absolute beginner?
I need to do a storyboard for a video for Uni for next week…
I believe it would be the ‘How To Draw Manga’ series?
Ask at your local import shops such as ‘Another World’ and ‘Gamestation’. I find one everytime I walk in, trust me. Even if they don’t have any copies they will order them for you.
Oh and if all else fails you may try ebay or amazon. ^^;
Good luck on your search. 🙂
