The image I had in my head when doing this was a field scientist combing through the woods and stumbling upon a nature sprite, startling the hell out of the both of them. Nature sprite flees, and scientist does a quick sketch in his notepad of what he remembers from the sprite (right down to the stunned facial expression). So if the picture looks kinda "sketchy", that's why -- it was intentional.
I made her body and limbs long, like a tree. Painted with J. Herbin Lierre Sauvage, diluted with water to get the various shades. Also, I made her eyes golden brown but you can't tell in the photo. Darn.
