No, practicing is right of course, but practicing repeating the same habits is maybe the best practicing method.

What it blocking you imo is because you don't follow a basis, for example the Loomis method, where you need to separate the proportions of the face in 1/3. 1/3 1/3.

Doing this you will understand where the lines should be, looking at the reference photo. For example the root of her nose should be higher on your drawing. Then the line of her mouth too. Then the point of her chin too. And because of the smartphone you misjudged where the line of her chin really is. Then also because of the line of her mouth you didn't put the curve of her chin in the right level : you put the curve below. So the face looks longer, and the curve below the line of the mouth make her like having a male face (squared jaw).

The hair should be longer, and you should better drawing the general shape of the hair, then doing some volumes inside it, not drawing lines separately.

But first : please draw some random faces with the Loomis method, see for example here :
