This was done for the Beast's of Yore collaborative project; a collection of artwork by 19 different artists depicting many strange, unique and mythical creatures from tales of yore. My beast is the Norse dragon Nidhogg, who eternally chews on the roots of the tree of life, Yggdrasil. My friend, Nate Newlon, wrote a short story based off this painting. You can read that story in the description of this painting on my DA page!
