Oh my, oh my. This is just getting too hard. A bit like judging peaches against pears, to paint a fitting picture
Both models look not only as perfect and beautiful as I can imagine any woman can look, they both radiate an air that makes them the champions, anywhere. The one thing that makes the different, it is a personal thing, right now, it is:
One picture is just perfect, the model, how the model is positioned in the background, how she dominates the whole background, middle ground and foreground
And the other, you might find it amateurish, but I think you might get my point this way:
The background is too "noisy" for me. The model looks - as I said - stunning, but the photographer should have picked a calmer spot
