I really like the first impression I get from her. The eyes are so captivating and drawing with such detail, as are her lips and her jacket collar. The detail in her hair as well is also rather impressive. However it's her realistic expression that really makes me enjoy thhis piece. Also just how innocent she looks.
However I see room for improvement too. I feel that the top of her head where the curve is could be lower. Her hair on the top of the head does not look poofy so much as her head on top looks bigger than it should be. While her lower region where her jacket is rather void of detail compared to the resst of it. Maybe adding some texture there would help? Otherwise it's wonderful disregarding those minor details.
