The first shot works for me. It certainly echoes a lot of the 'nymphs of the woodland' sort of thing and the poses, gestures and expressions of the three models are in harmony with the sentiment of the shot.
The second I don't care for at all. Chances are they are both candids done after a more formal shot but that is the serendipity of what we do — sometimes you are the pigeon and other times you are the statue.
Who gives a flying frig what these were shot on? Whatever the artefacts, they form an integral part of the statement being made. I guess there are also imbeciles who'd be concerned with whether a shopping list was written in biro or fountain pen; on plain white paper or a ruled yellow post-it.
We see an inordinate amount of technically proficient and aesthetically challenged shit with great regularity here. Better to have made something as cohesive as the first rather than the cold stale porridge presented as masterworks we are so often subjected to.
