Here are some of my environmental concepts for the Magic: The Gathering expansion Throne of Eldraine, which came out last year. They show some of the process that leads up to the concepts in the worldguide that gets sent out to the many freelance illustrators that work on the card set. It's all pretty sketchy, but it's a quick way to play around with ideas before spending time rendering up more polished illustrations. All images shown with permission of WOTC.
