Girl with Hammer

So I was nosing through Yumi's gallery. I saw a great piece of art with a girl with blue hair and a huge hammer. I said the myself "Girl. Blue hair. Huge hammer. I have GOT to get me one of those." Well my search continues, but hey, I drew a picture of one. Sure its in black and white, but I assure you her hair is indeed blue. And I also didn't know if I should submit it or not, its not really finished, I want a background for it. But I'm stumped. I'm hoping you guys will help me with that. I think I like this one, I really need to think her up a name...Well, comments/suggestions welcome...
