Movie

So i watched this movie awhile back like 7 years ago and it was about this girl and this guy the girl had blue and black hair and the guy had like dirty ginger curly hair and the girl dyes her hair alot and this movie is like videogame comic like. Its real people but it has like the little bubbles like in comics and one scene i remember is the girl had like a usb chip or something on the back of her neck. And another scene the guy was in the snow at night bang his head on a pole thats wooden and i was wondering if anyone could help me find it. Thanks
