When you first came up with your comic or novel, what was the first image that popped into your mind? Was it a character? A setting? A panel? Or a series of panels?
I'll go first: In my ancient adventure comic, Enoch: The First City, the first thing I imagined was a boat falling from the sky, starting out as a little pinprick and getting bigger and bigger and bigger, until it looked like it was about to crush you underneath.

The rest of the story emerged as I imagined how the boat got up there to begin with. How about you? Where did your story start?
