Graphics: I loved the frame by frame. Your characters looked fairly realistic, but you could probably work on adding some more detail, including shadows to the faces and body, if you want to give it a fully realistic effect. Maybe downsize the brush tool a bit so you get a more fine line and can fit more detail. Otherwise, it was animated and drawn nicely.
Sound: The Kill Bill music is a compliment to any film noir styled movie. Nice choice there. The sound effects were top notch. The guns sounded nice and crisp. Maybe work on the voice recording quality though.
Style: The black/ white look was a good decision on your part for this film. The violence is more straight foward and intense when blood red is the color that stands out most. You presented your characters nicely, and the main characters moves were both suave/smooth and stylish.
Story: Well. This one, story wise, was extremely generic and cliche. Some guy goes and kills a bunch of bad guys with guns blazing. Maybe add a bit more of a story to the next one. A rich plot can make a movie, when no plot at all can break it.
Overall: Good job. Cold Blooded Killer is exactly what it sounds like it is. Some guy who seems to have no remorse for the people he kills, and is a badass at doing it. Good job, you chose good colors, presented nice action sequences, and the overall mood was fun and stylish. The only thing I can really complain about, is the "kaboom", and the black and white scetchy clips at the end were extremely random and completely killed the awesome mood of the rest of the movie. If you make something as good as this, you want it to end on a strong note, not an abrupt rushed ending.
