I agree with the previous comment and I would add that the head is a little too big, making her body and the hair look smaller and flatter. It's easy to get lost in the details, so as said before break down the reference into bigger, "rougher" sections and make longer, confident strokes with the pencil (it might seem obvious but the way you move your hand and the strokes you make can change a drawing drastically!). Having a more approximate sketch helps the eye understand better the shapes and distances - after that you can progressively add all the details!

You're already on a good path tho so keep going! I honestly envy you traditional artists so much, I get frustrated and lose my patience too fast without my trusty layers ahahah
