You've created a Monster! And it looks very much alive with the eyes! I initially thought it was a manipulated photo until I looked more closely, best thing to make him more convincing is to work on the skin tones on the cheeks as they look more muddy and unrefined, .. the forehead I can see finer details of creases and the slight shadows of the heavy brow.

The Hair I'm not sure how I can give a advice on.
