This is probably my most ambisious Tarot deck yet. I'm working on my own version of the Thoth deck by Aleister Crowley. I've always liked his interperation of the classic deck but hated the artwork. 
The Book of Thoth is a very long book he Crowley wrote about his Tarot system, he gives new meanings to the cards, and name some of them differently.
It takes a lot of research and due to the very alaborate syle of illustration, it'll probably take years before I complete it if at all.
