It is remarkable how angle and distance can effect a photo. In this case, the first photo makes her belly look absolutely huge:
While the second photo, which was taken from around 10 feet further back, but zoomed in so she occupies the same approximate space in frame, is more flattering and a better photo. Of course, the light is a bit more even and more airy, and she is more symmetrical, which I think helps this pose com off.
