Remember that the head (and hence the face) is made up of planes. You can use this simplification to improve your drawing. Identify these planes (you can find references for this in a lot of places, even in Proko's free content on YT) on your reference and use that as a framework on your drawing. In this framework, your lines should define volumes (i.e., making the head look 3D by adding depth, not just simple line art). As a more concrete example, in a three-quarters profile view, on the side farther away from the viewer (left side of reference image, model's right) the depression of the eye socket creates a strong curve starting from the forehead continuing to the subsequent re-ascension of the cheek bone. You didn't capture that curve in your sketch.

Hi there, I try to help you, but I don't speak English well. Just like this

Try flipping the image upside down and drawing it upside down. Sometimes our brain gets so caught up in drawing familiar features like eyes, noses, etc., that it forgets to look for the actual shapes in an image, and drawing something upside down can help trick the brain.
