Spinal Maintenance

Walter Girl upkeeping The Spine! Done with a mechanical pencil on some printer paper.  I'm well aware that this isn't quite to par with what I've done before, but it was fun to draw and men are hard to do. However, to whoever can tell me what is wrong with his face, I will love you forever. Not so much why it doesn't actually look like The Spine's face, but in more of a general sense. There's something wrong with its basic shape that is not correct for a human and I don't know what it is. 

I'm thinking about adding some color to it later. Then again, I always say that.
