I'm not sure how this happened... I was drawing this page, and it was LONG. There's nothing special about this page though.
There aren't a million characters, or complicated objects, or difficult backgrounds. Kind of elaborate, but I've seen worse.
I was almost done when I noticed that I was drawing page 16 and 17 at the same time. I spent hours flipping from a page to another and managed to forget that there was more than one.
I hope there's a medal for a feat like that.
