You can see how rough our boards are. Their purpose is mainly to tell the story, not be finished cleaned up layouts.
I draw my boards at EAT on Magnolia during breakfast, while I don't have to think about anything else and no one bothers me. I scribble them out as fast as I can, just trying to get the gags, continuity and story to flow.I use crappy cheap lined writing pads and BIC medium ballpoint pens, so I don't worry about wasting good paper. I want to draw fast, not worry about construction too much and not worry about clean lines at all.
This below is a pencil storyboard sketch on fancy paper and is less lively than my crappier scribbly ball point pen sketches on wood pulp.
Here's a couple of Jim's setup idea sketches...
Jim has his own theories and techniques and they make his style unique and fun.
More of my continuity scribbles...(not in continuity though)
If you don't have to draw perfectly clean and on-model while you do storyboards, then you can access the part of your brain that thinks about STORY, rather than clean up.
A lot of studios today have a department that's called "storyboard" but they don't use storyboards in the same way that they were originally intended. They use them instead as mini-layouts, that are supposed to be blown up larger and used as keys for the Asian animators.
"Storyboarders" don't usually get to do story anymore which is a shame and an irony. Writing with pictures is a blast and brings so much more to your stories, than merely trying to describe everything with words.
It's also hard to draw good detailed layout drawings small, so the end result of storyboarding from scripts, is both bad storytelling and bad layouts. The poor storyboarders don't get to have much fun in this system. I'm sure somewhere there are a couple exceptions.
A lot of lucky accidents happen while doing rough storyboards, and the trick is to preserve them in the layouts. When taking the idea sketches and blowing them up to animation size, tightening them up and flipping them from pose to pose, there is a great tendency to tone everything down and lose the humor and spontaneity.
In fact, every step of the animation process has a dangerous tendency to lose some of the life of the previous step. I have been working on a science to combat that for my whole 30 years in the business.
Finding good layout people who can draw with life is a blessing from above!
A side note:
Many times in a cartoon, I have tried to get funny layout drawings inspired by the storyboard to flip right and lost the humor in the process. In those cases, I would just use the funny poses, even if they didn't animate right. Lucky for me and the rest of the industry, Bob Jaques and Kelly Armstrong developed techniques to smooth the connection between 2 not very well connected poses. This technique (in simplified form) amazingly has become the standard for most Flash animation today. Carbunkle's animation used a wide assortment of techniques and they customized many scenes, but a couple of their tricks (without the custom tailored thought) became the standard style for whole studios down to today.
That's why you see so much "snapping" from pose to pose today, where you antic and go past the next pose and settle back into it. (You are in effect, avoiding the inbetweens) It's one good technique that's useful in some cases, but it gives me a headache when I see whole features use it to connect every single pose. No variety in timing or emotion. Every emotion using the same timing trick - or handful of tricks.
If you watch an old 40s Warner Bros. cartoon, you will find all kinds of custom timing and posing that is designed to fit the story and emotions. They didn't use a handful of tricks. They really thought about every scene and its context. Of course we can't afford to do that with today's TV and internet budgets, but they could easily afford it in today's animated features, if people in charge had the will to do it.
