So, first the dislikes, her foot. It seems to be grass in a certain spot. I also dislike the two odd white pieces in the background grass. I'm not sure if that's just some passerby objects or white flowers. I also kind of don't like how her right hand looks but it works with this image at the same time, so on to the likes.
Likes: I love this photo regardless of my dislikes for certain things. I love how she looks so surreal. As if she was born to be in that exact spot, painted by the angels. I absolutely love how her hair is cast in both light and shadows. The model you chose for this w Is absolutely breathtaking. Her eyes even though they can't really be seen head on, look gorgeous. The dress and hat work perfectly to compliment the scenery, in my opinion. What stands out the most is what you'd want to stand out: the girl all by herself.
The way her eyes are not looking at the camera makes you think, hmm, what is she looking at? Did you take this photo on a whim because her beauty is captivating? What is she thinking? Endless questions can be created. Many stories and ideas could come out of this one photograph, and I think you did an excellent job on capturing that.
