Okay, I've got 2 minutes of storyboarding done! It's a rough time estimate, as I'll tweak all the timing when it's done, but it's giving me a good sense of flow. As frustrating as it is to try to draw it all out (I want to build everything instead!) it's been good for thinking more about camera angles, length of shots, etc. Attached is one of the frames - as you can see, very very simple drawing style - the cat's sneaking back out of a cupboard after getting stuck inside, as seen through a Polaroid camera. We've actually got one kicking around, so I might try and see if I can take pictures with my DSLR through the Polaroid view finder for the shots - if not I'll fudge a frame for it.
