mate thats a 100% improvment compared to your last.
No real crit, just remember to keep you geometry clean and flowing nicely.
Make sure you got the basic features of the face correct before you add more poly.
Theres nothing worst than have too much poly, and having the proportion out somewhere.
I havent modeled to many characters, so im not the best one to give your crits on you work.
Its looking good. Im glad you started again.
