I like them :) they are nice and soft ( I can't seem to get my drawings soft like that). The only thing I would say is that try to get more black into your drawings. Just remember that your drawings should have from number one to ten ( one being white and ten being black) if that makes sense ( so ten could be apart if the eye and one could be the highlights)that way your drawing will have a lot of different tones to it :) hope that makes sense.

THe eyes look really nice, my only suggestion would be to darken up the pupils, the lashes and the lines around the eyes, to bring them out more and add more contrast to the lighter shaded areas.
The head has nice shape to it, but again I would just darken up some areas
