Great progress already!
But before you get too far with the work on the head, i might advice to do just a little more work on the head first.
The top part of the nostrils need some attention, and the top triangle above the nose and between the eyebrows is kinda missing. If you look at the picture of yourself, you see a kind of almost triangle shape with the wide part between the eyebrows, and the thin part between the inner sides of the eyes. These are the kind of shapes that make the characteristics of a face.
Plus you got some strange shape in the forehead. It’s not flat enough to my opinion. You can see it clearly in the last render with the glossiness on it.
Last remark: i think the jawbone needs to be wider.
cheers
