The Nature Warden is now available for pre-order on the Paizo web site. She represents a prestige class for Pathfinder detailed in their new book the Advanced Player's Guide.
I originally saw the art when the book was initially released at GenCon. Upon returing from the show I set about to make a spec piece to see if I could catpure the essence of the character. After a discussion with the art director over a couple of details, he submitted the piece to Paizo. They seemed very enthusiastic over it. Hopefully I'll be able to do more Pathfinder pieces soon.
