I really struggled with creating my own characters. I was afraid I had no imagination, and that I would end up being totally derivative and just copying forever.
But the turning point came for me when I started illustrating my daily emails and that was a game changer. It meant I never ran out of ideas and I developed deeper, more interesting characters.
Everyone learns at a different pace, and some are better at some things than others — but everyone alongside me has learned to draw good cartoons in their own style.
