Greetings from the CC. I like your subject, I think pregnant women make radiant subjects. Your shot conveys a real simplicity and subtle beauty. Her face really conveys all the feelings of pregnancy, lots of emotion. I think your shot shows a longing for the child to be swinging with her. However I would of cropped a significant amount off the top, at least to the fence and maybe a bit off each side to help maintain the shape dimensions. Losing the right top (over-exposed) would of helped a lot too. This is not probably a wow photo, but I think it is a personally appealling shot (more so to her family and friends) tho it does have a very human element to it. Hope that helps a little, keep shooting.
The lighting on this is a bit harsh. A different time of day would help with that. Also, I don't know the lonely pregnant lady and thus this shot doesn't hold my interest much...
