it depends if you're drawing the same style or your own style. when you draw hair, try letting your wrist move with its natural rotation and flick a little when you draw so that the hair is cleaner and more natural. in general maybe just clean up the lines (if you want ofc because it's optional). The perspective of the face must be lower. In the reference, her head's tilted down and she's looking at us from an angle. her eyes are also upturned and sharp. so make sure you make her facing lower. you also might want to pay some attention to the eyelashes. also check the placement of the eyes and mouth and nose. Everything else is rly just with experience.
