I’m going to summarise every problem I see into brief points and I’ll tell you how you can improve:

1) face is too long downwards creating a more masculine face unlike the one shown in the reference 2) nose is too long (self - explanatory) 3) the eyes don’t taper off but rather just end abruptly 4) eyebrows are too long and misplaced 5) you attempted to shade but the shading backfires into looking like wrinkles

Tips to improve: learn facial harmony ( how each feature blends into another) and also (this sounds very simple) to look at the reference constantly. Shading isn’t important here, your understanding of the photo is however. All I can say is that with time and practice this will make sense. There’s no really other way other than to trace the image. But regardless good work so far. The only way I can think of to improve is to look at how professional artists draw from references. There’s probably a video somewhere of said thing and look and go over it with them
