1. Art Description
Here's the original art description:
Location: A field of nettle-wheat near the border of a creepy forest
Action: Show an elf "nature-priestess" of your design, male or female. He/she is a healer and a master of herbalism, a mage who gets his/her power from nature. Show this figure casting a spell; perhaps leaves made of light swirl around his/her

In the end, Steven took the bottom sketch and filled it out nicely, as you can see.
