to me she looks a little old here. something about the neck and the colors. like how when your grandma puts on too much makeup and her face looks too pink in places. I wish you had spend a little more time on the crown on her head and put a little more detail in it like you did with the chest yolk.
But her eyes are really pretty and the little fuzz on the ears looks cute the horn shading makes it look 3d and the way her mane is flowing around gives a dream like quality.
