First of all, when I took a look at the controller, I thought it was a picture. then, by examining humanly mistakes (they can't be avoided) I believe this was freehand drawn. the bone structure is neat, but it could use a little more variation. I like how the buttons are integrated with the 'chest cavity', and how some arteries/veins are lopped off. However, the middle button looks flat; I was expecting an orb or sphere. the start button as well; it looks like a sticker. otherwise, this was a wonderfully executed piece of work. Congrats to a job well done!
