These are the things that I see.

1) There should be an extra loop around the mouth to the nose.

2) There is too many polys on the forehead above the nose. Try to terminate some of them. You have too many polys in general for the shape that you have now. Lowering the number of polys will make it much easier to tweak.

3) The pole on the temples won't smooth nicely. Try spacing out and redirecting some of the edges in that area.

In general, you want your faces to be as square as possible. Some times this is not possible, but it's good to try.
