Here are some concepts I made for Ashes of Outland!
One of the most lesser known parts of working on Hearthstone and also one of most exciting in my opinion, is definitely creating the art style guide. For every expansion, we make a guide to help the freelance illustrators understand the mood and the flavor of the upcoming sets. Adding background, props and creature designs works to unify the illustrations that come from many different artists, and it's always a pleasure for us to recognize a design we made in a Hearthstone illustration. So cool to see how the other artists use and redraw in they own way these elements! Had a lot of fun with this expansion.
