And I though that was his mouth?

This image is very simple, which doesn't mean bad in any way. It just... _is_. His facial expression really shows some emotion (if 'whatever' is called one). Although the light-brown colour works very well with his face, maybe the shirt and his hair could've used another colour? Some dark gray for the hair and light/dark green for the shirt? These are very small things, which don't really ruin the pic. :)
