I believe "Tank Girl" is referring to an actual character. It's not one that you or him made. I am somewhat familiar with the character. This is a great picture because of how ambitious it is. Wait, shouldn't this be under Egoraptor's profile? Well, it's okay with him.
It was pretty easy to tell it was made by him. He seems to draw women in a similar manner. I'm sorry, GIRLS would be the more appropriate term here. A double image, is that what this would be called? I just wish she was a little hotter, lol.
