I affectionately refer to this card as the "Release the Kraken" card. The Rider-Waite deck features the lunar orb, two towers in the distance, two frolicking or fighting dogs, and a crawdad. In an effort to streamline the image, I removed the towers that appeared in my first version and enlarged the Kraken, in addition to changing the background to reflect the new color scheme.
I consider this drawing to be final. It's one of my favorites.
