I forgot to mention one big change in my drawing style: just because your character is moving fast does not mean that you need to draw it quickly. Sound obvious? Not to me! When I drew a character flat-out running, I felt I had to mirror his energy by drawing really really fast. I got some great wild lines, but it always looked a little underwhelming. Turns out, the slower you draw, the more control you have. There is a balance to it, of course. Draw too slowly and you end up with lovely ink blobs on the page that never dry. That doesn’t work unless you’re Jackson Pollock.
