Awesome job, I liked the pics and story. I especially liked the story and the amount of detail you used to describe her transformation. I also liked the methods through which she gained her powers and would love to see the witches who respond to her call. Maybe each of them can have a specialty (fire, water, etc.)or a specific method for gaining energy. I really liked the idea and would love to see a series based on the various members of her coven.
Good :) it's another of those things I need to file under "to do later" because I have ideas for several other things in my head at the moment and, if I don't write them down soon, I feel like they'll escape. I will defiantly do more on these series's that I'm starting though haha.
