your skull shading is fine. the latest update is fne as well. i do recognize that those are from dynamic anatomy. i totally don’t mind seeing you using that book for reference for shading study. but keep in mind that dynamic anatomy talks about anatomy, in a somehow exagrate way. eventually when you shade a face, there need to be more than just bones and muscles.
Today is another drawing day, played with lighting and refined details.

Thx a lot for the exemple Jack very appreciated 

draw woman with ref, then draw woman without ref. then draw woman with ref, then draw woman without ref, then draw woman with ref, then draw woman without ref.
you draw two women with ref, then you go draw a guy without ref. It’s like the trainee showed you twice of how to make a chicken burger, then you go make a big mac on your own. Does that make sense to you???
