Generic head practice

Practicing head construction but having trouble placing the features mainly the eyes are small when I draw them, like they look proportional to the face but when it comes to drawing it becomes messy with the pencil and I can't the iris and pupil with enough space and the mouth looks to far from the other features because I understand the mouth is supposed to align with the mouth or is my jaw too low?

Sopranos sketch

I feel quite happy about how this turned out but I would like critique on any ways the form or way the features sit on on the planes etc might be off. Also things to consider when constructing the head in this way would be helpful. Tips on linework or rendering with biro also appreciated

Gas Giant

I think there is something wrong with the face proportion and rendering …also cloth anatomy and hair
