yep, just looks like the edgeloops need work as the general head shape is ok.
Save a copy of the head and just be ruthless, get the split poly tool and go to town playing with the lines as shown on the image NextDesign posted. You'll probably find that many of them will line up with what is aready good and there will only be a few areas where you need to rework other lines. I'd probably knock out some of the dense vertical lines in the forehead just now so you dont end up having to move too many vertices around later.

good stuff
