You don't need to draw.

I've found some storyboards for you online.

My problem with most of them so far is they don't include enough information.

They look good though.  Which is probably partly why they are available on the web, since they advertise the artists ability to draw - which has, let me say this loudly, absolutely nothing to do with making a good storyboard.

NOTHING.

Since we have fighting, here's a fighting storyboard, and a bunch of other storyboards.

You'll notice how the artist uses the frame of the storyboard like the frame of the camera.  If it's inside the frame, we'll see it, if not, we don't.  This allows him to focus on the dramatically important information in the scene.  There are some good stories here about who he was doing them for and what was expected.

You can click through the pages to look at other examples.
