Just thought i’d as for some advice about this face model, it started off as a topology-exercise, but the form itself seems like there’s something not entirely correct. Any advice/critique would be appreciated. 
Kind regards

It would help if you added some skin folds or wrinkles around the eyes. I also think the forehead is too tall. And the nose needs to be more rounded. The hair looks like it belongs on an older person.
The topology looks good.
