Admittedly drawing faces is a thing that can be learned very intuitively, as we've seen the faces of many people throughout our lives and it is easy to tell when something is wrong. The first thing I suggest is that you should try to break the face into simpler forms, you can try to simplify the facial features with simple forms (like the nose as a simple box), and you can try to break it down into planes. Avoid drawing flat shapes and do your best to always use 3D forms.

All of this should be done from imagination, this may sound daunting at first but you will learn a lot by trial and error.

And if you want to complement it with an actual method to draw the face/head you can search for the Loomis method on the internet, I personally have never used it, but I've seen plenty of people recommend it

Looking at your work I like to see that you are drawing your marks with good confidence but they can be bolder, right now you seem to be focusing on the individual parts of the body like the arms or legs and drawing individual lines for them, you can try to draw longer lines to that capture the flow of many things, you can try to draw the main line of action first, as another user suggested, you'll find that it usually runs all the way from the head to the feet, once you have drawn that you can use it as a guideline for further strokes, try to focus more on how the reference pushes your eye around, rather than focusing on simple elements.
