But the eyes are too low and it looks more like an alien than a human. Or the top of the skull is too high, can't really tell. And the cheeks need to be a little rounder.
It's not the eye height that causes it to look like an alien. Look at the second picture, it looks like a nice cartoony but semi-realistic human head there! I suggest to try changing the distance in between the eyes and/or change the shape of the eyes themself. Humans normally do not have such sharp defined eyes, eyes of younger people tend to be rather round. I would suggest making them more round and the head does look like a younger person,
Cheers
