I am very new, but here is my opinion:
She is DARLING! She looks like a little Christmas fairy
At first, what distracts me is the shadow on her face. Is there a desk lamp of some sort that you can put on the other side of her? The light from the door is excellent.
Maybe try taking the shot from a different angle? Does she have a favorite sound that you can make while shooting that will get her to laugh? My daughter loves it when we act like total fools for her :P
Like I said, I am pretty new so I hope this helps....
