@Ferg - I love your stuff man, really great style and personality to it. @Harry - I'm not sure what the purpose of the mesh is for(sculpting, animation, etc...), I don't think there is too big of a problem with the forehead loop. I think though you should have another loop going from his upper nosrils to around his mouth.
Man, im so fucking out of the loop... so much badass stuff on the last few pages! I revived an old picture and mixed it up a bit, for better or worse who knows.
@D2king10: I would take the edge loop you have in the middle of the nose that stops at that 5 point poly and continue it around and up the cheek up to that triangle edge you have up by the temple.
Its not even a joke :( I might make a thread out of it because I'm gonna be going whole hog on this;- zbrush, rigging, animating; I've tried to go for my own topology to get a nice balance between polycount / animation/ smooth loops
