Looks fantastic so far, bro.
It seems you're picking up on his/her style.
Like SlyCooper said, proportions seem to be in check and the basic concept is looking sturdy.
However, just in my opinion, the robotic looking thing on her crown/hat, doesn't blend too nicely with the character. It's cool, but I'm not sure whether or not it would compliment your work.
But besides that, I love the face and the tattoos. I also really like the idea for the hair; very clever.
Please please please keep it up. This will look phenomenal when it's finished.
