Don't think I ever seen your other pictures so I can't comment on how much you've improved. However, I can comment on that these photos are very nice! I like how sharp and clear each one is. With that said, I don't really care much for the head tilt in the first picture, makes me tilt my head to see her face. Also, in the second picture, there's one stalk of wheat that is in front of her face which is very, very distracting.
