Based on the artwork from Shiantu

This is my second collaboration with Shiantu. I really like his paintings.
I was very attracted to the idea o this immortal character waiting endlessly, guarding a higher being, or an entrance to a realm. I had a similar feeling with some characters from Dark Souls.
