This is one instance where I start with a sketch I did either on my iPad in Procreate or on my computer using Sketchbook Pro and turn it into a traditional Pen and Ink drawing. As a professional storyboard artist, I don't get to draw much these days using traditional methods as I did when I was younger, so it's always great to get back to the simplicity and tactile feel of traditional materials. It doesn't get any more basic than pen and paper, and plus there's no "Undo" button to bail you out.
