Your coloring is great so is your shadowing.
I have a couple of problems with this one haha. But hopefully you'll (unless you already did) grow from some critique.
The lips seem a little low to me also it seems you gave too much
space under the jaw, If you would of drawn the start of the neck closer to the chin it wouldn't make the face seem so forward.
The last thing is the ear, You should always take into account that the ear ends at the same length where the nose ends. Also if you run your fingers up your jaw bone you will see that ear is right next to it.
So if you would of brought it up and moved if forward if would look just about right. Also I suggest taking a picture of yourself of a face pose that you could be struggling with. You would be surprised how much it helps.
