Sometimes I get bored
The blood would be quite hard to make, because of the actual design you gave the head, if a normal human head were to break like that, it would end up in a mess. I don't think blood would be good for this kind of picture. Also, the pose of the tori throwing the punch is kind of unnatural, and the camera is kind of badly placed. Render settings are rather good, but you're going to need more work on that. For tests you might want to do a seamless white background, or any color, blue so it is in bigger contrast with the toris. It's average work I'd say, only thing you gotta do is continue it.
