For me, each book is kind of like a silent film. If you were to remove the words and just look at the pictures, you should be able to tell what the story is about without having to read a word of text. That's what I think I brought from doing artwork for film to doing artwork for books.
Mr. Donald Trump talking about the US Mexican border, he's not doing anything new or unusual. It's something that's very much in the air and perhaps always has been. The Great Wall of China has been there for a great long time. People have always tried to keep foreigners out. There is a very natural desire, once you've got somewhere cozy, to keep it to yourself, and equally there's a very strong impulse for those who are not at such a safe and prosperous place to try and get in. It's been creating conflict throughout human history.
