Different Phases of Azula

I've owed my friend a drawing for a very long time. He wanted a picture of Azula, so I gave him three. I wish I took a little more time and was a little less careless, but I like the way it turned out. Gosh I love my grey markers.

Michael Dante DiMartino and Bryan Konietzko own Azula, not me.

Here are the reference pictures:
