I think the notion of a robot vampire even existing is funny. I do kind of wish this had some action in it. Now that I think about it, I guess being a robot probably wouldn't create THAT much of a conflict with also being a vampire. It's just weird to imagine robots sucking blood. I like how the regular robot has that flathead design. Come to think of it, most of your designs are like that.
I guess it's just more notable here in that there isn't a lot of detail in his hair. It's a strange atmosphere you've created, with how everything is green. I hope this did well with that band you were talking about. You probably could have done without it being shown in "widescreen" though. I like how the robot just crashes through his coffin.
