It's an alright tut. Not much to it since its so short, you didnt even mention how to shade or lighting. Just view (ie Perspective view, the view from which the subject or object is being seen).
Also, the eye placement is halfway down the skull. Basically dead middle. You placed em slightly above mid-line. I know this seems overly picky but its gotta be right to be a tutorial (At least we can hope so). You did place the eyes far enough apart because the eyes are suppose to be the eye-width apart from each other.
I'm a fair artist at faces but I'm not going to "show-off" those faces because their hand draws. Descent tut none the less just add more details! Keep up the work on the tutorials. Details!!
