Nyssa, the Scandinavian name that means 'elf', is spelt with a Y. I've only ever seen it spelt with an I in one other place so I was quite shocked to see this. Nice art by the way. How long have Wizards of the Coasts had a character by this name?
Nice work as usual. Her face is rather distinct (in a good way) and very nice job with the cloth drapery, too. The tree bark seems a bit scale-like, and I'm not too sure about the look. It vaguely looks monster-ish, which I suppose I can get behind, so hm.
