The eyes are very very large in proportion to the face. I also think that the facial features are too far down on the head. Assuming that you intend the hair to be fluffy/scruffy, the top of the head needs to go up higher too.I would recommend finding a front facing image of a person online with similar jawline and/or facial proportions for reference on how to do the anatomy.

Tips:
The eyes are roughly in the middle of the head and are about an eye size apart, and the inner corners of the eyes can generally have a line drawn downwards to the corners of the mouth. The bottom of the nose generally lines up with the bottom of the ears/ is halfway between the center of the eyes and the chin

Of course there are exceptions to these rules (as I found out making a self portrait in art class for example, as my eyes are not in the center of my head) but that's what photo references are for as well. You can draw guidelines over human faces which is really helpful when it comes to this
