I believe that someone above mentioned a "mythological" category, and I'm of the opinion that it's definitely needed, there are many who do mythological images ... my latest of Bastet for instance, does not necessarily fit into the "spiritual/religious" category, although some may argue that point, but it certainly does not belong in fantasy. This has GOT to be a very difficult list to create and refine, but I think it's a wonderful beginning and can only get better over time. Thanks!
