Nice. I think the "look" is more affected by the length of the face. In pretentious art classes I was always taught that, proportionately, the distance between eyes (for humans) is the width of one eye. Not just the eyeball, but the skin that comprises the corners of eyes, etc. This rule of thumb seems to work pretty well in real life.
Anyway, just a random thought.
Nice job. That's a great look for Batman. :thumbsup
