Three photos of the same puppy, but showing different virtues. The first shows a lovely overline from the reach of neck to the wither, smoothly over the back into a sloping croup.
The second shows better front and rear angles, but a peak in the overline which is not naturally there as you watch the puppy free moving detracts.
The third photo shows a nice overline, the best hind angle, but no front. I like the three photos for the reasons I've given, but overall I guess the first is more pleasing to my eye. Feel free to disagree!
