I find myself looking at the facial expression and pose to understand the mood.
Would a different model in the same pose make a difference ? If a different body changes the meaning, is the whole point of the picture to evaluate the model's body ?
The focus of this photo seems to be on the femininity of the model. It is not a front portrait but a side one. The viewer does not make eye contact with the model. Thus we observers but are not intimate. She keeps us at a distance.
She is not in a comfortable pose. Slightly raised above ground, she has an arched back. She is not sitting but leaning. Her hair is not in a casual position either. I have very long hair, and I have to gather it and move it over my shoulder. It does not move from my back to front on its own. She has carefully moved her hair just so.
The pose is unnatural. She would not assume this position in her everyday life. What does that mean ? She has set herself carefully in a position she wants to be viewed (or the photographer made her). What message are you sending ? Is that a sigh ? It doesn't seem like pleasure. I find that sigh to be vain. It is not natural, but a pretense. To evoke sympathy ?
People seek out frankness and honesty. Frank and honest people are popular. And the opposite - artificial people are not.
The portrait evoked in me a sense of pity - the person cares too much about what others think of her. She is self conscious and has built a facade of how she wants to be perceived.
That is a pity. The person is beautiful. If she chose to be "just herself" instead of worrying about appearances, she would be much happier.
I think you're drawing too much from the shot. The pose is that way because it's more interesting and just plain sitting. The pose is unnatural, which is why I did it. If everyone posed the same way all the time, it would be boring and my pictures would be boring. Part of the reason why I love modeling so so much is because I like to do unnatural poses. To me, it makes the picture more interesting.
