Storyboards for
this animation. See the finished(ish) animation for more of the story behind this.
You may notice that the storyboards feature right-facing animals but the animation has the animals facing left. This was a conscious decision: for the storyboards to "read" better, I thought the animals' eye lines and actions should point towards the next frame -- however, I am right-handed so it's easier for me to draw things facing the left, and for the animation frames I didn't want it to be harder than it had to be.
Drawn with an Intuos3 Wacom tablet in Illustrator CS5.5.
