Your using more lines vs planes. It's giving it a more 'animate' look. You'll need to create lines through the different between values to give it a more realistic style.

think in terms of the shapes--quick rough for guidance...notice I didn't really put in lines...

same concept...the big shadow shapes
I like to just shade the whole thing usually first because eyes are sunken in.

Youre looking for outlines and not shape/structure. i recommend sketching out the structure of the head before you even consider details

You can also lighten up areas you shade to with an eraser to carve out shapes too.
Don't be afraid to really block it it in.

Its also easier to build up gradually that go hard all in scribbling and then try and erase it
