Old-school doodling

I don’t start my process digitally. Using a cheap sketchbook, I draw A LOT of doodles, until I find one I can work with. I keep the doodles small and quick (less than five minutes each). If one sucks, I move on. I experiment with shapes, shadows, and line work. Tip: Carry your sketchbook everywhere. If you have down time, pull that thing out and throw down some lines.
