Green Lady of Perelandra

I guess this can be described as fan art? This originally was drawn as the Green Lady from C.S. Lewis' book, Perelandra. If you haven't read it, it is AMAZING. He wrote a sci-fi trilogy and Perelandra is the second book (and my favorite of the three). However, my version of the Green Lady is much more menacing looking than the one Lewis describes in his book.
