I think you got expressions pretty good but definitely should work on fundamentals (basic shapes/anatomy, Artwod roadmap is great for it). 1. More confident lines would definitely improve overall look of the drawing. You can practice it by filling a page with straight and wavy lines as well as circles every day (see A). 2. Other than that there are anatomical issues like head being placed on the neck too far back (neck should be roughly half of head width from the side, see B). Ears should align with top eyelids and tip of the nose (see B). Chest should be lower. Shoulder is slightly too big for her and positioned too high/in unnatural place. Try such pose yourself in front of the mirror and observe what feels natural and what doesn't. When you post photo of traditional drawing, try to take picture from above - otherwise it is too distorted and hard to view/leave feedback for. | Artwod Feedback
