You have the basic shapes down very nicely.
Your edge loops around the eyes and the lips are too close together, thus giving you the “hard” edges that you see. Try selecting a few of the loops around those areas with “SHIFT+ALT+RMB” and then turn on the “Beauty” button in the EDIT menu and then press the “Smooth” button 2-3 times. This should help get rid of the hardness there.
The eyes look to be a bit small as well. Open them up some.
Can you post a wireframe of this head too? Would like to see your topology a bit more to make some suggestions on that.
