Alien Cyborg

I often just start drawing odd things, and so when I started thinking about robots, I started drawing this guy and got to about the neck, but stopped as it became more organic.  After I started it, I liked it enough to keep drawing a couple days later.  This is what I came up with, an alien cyborg...thing.  I'd like to make it over in Illustrator eventually.  Only used a mechanical pencil, printer paper, and a slightly terribly cell phone camera.
