There’s not a lot wrong with this shot. It’s a nice portrait of a little girl, although she looks kind of sad, as if she’s about to cry.
I think compositionally I would crop this heavily from the top, maybe even into a square format. This places her eyes in the top 1/3 of the shot and gives it a better balance in my opinion.
Maybe a tad more sharpening around the eyes, a little bit of added contrast and you have a very nice portrait.
Well I’d say that has definitely improved the shot. I think I’d crop a bit deeper though, even though it may seem drastic at first. I used to hesitate to crop that way myself, but now I try and go straight there in camera. I think her eyes are still a little too central in the shot, and her eyes are the focal point.
