Cool, very stylized and bright. A bit of proportional problem regarding how thin the arm is compared to the body, but it's all good. Can I ask why does she have "brain" on her shoulder?
That's probably because I redrew that arm too much and I said screw it. As for why that's on her shoulder, it would probably make more sense if you knew there are several symbols on her lol they're more like characteristics I guess you could say. It used to be a kanji for 'will power' but certain storyline problems made me change it.
