Ouch, that pointy chin could hurt someone.
The hair could be at least a little bit more defined, I mean, look at the way the hair is going --> and then look at the hair on the face, it hasn't migrated that way -->
Head band - well, lets just say, we don't wear them diagonally, nor would they be that small, look at Naruto, he has a nice thick band, that sits horizontaly on his head, not diagonally.
Also, hair should be over the band.
I have a sorta feeling that this is not really an Anime face, but sorta a american try-hard go at anime (no offence, its just an opinion).
Any other things to point out?
Being a critique, I would rate this a 1 1/2
