You clearly know what you're doing when it comes to using your camera and directing your model which is great. I love how simple this image is, just her the rocks and the sea Her pose is great too, she looks relaxed playing with her hair and feeling the cool breeze on her neck. The crop works well but I feel like a rectangular crop would have worked better? The subtle tones work very well and the soft focus on everything but your model really draw your eye in. I also like the textures of the water, the rocks and then the models skin and clothing adding something soft to the images. One thing I must say is that you've gone to all the effort to edit this and shoot it and it's worked well but it reminds me a bit like iPhone instagram photos, just my personal taste puts me off a little bit, but it doesn't detract from the beauty of the image and the tones make me think of a lovely summer morning.
How beautiful! The monochromatic background and blurring around the edges give me the feeling that her world is just revolving around her. She looks so serene. Yet despite this, for whatever reason, the photograph does not come across as hopeful. Another commenter mentioned that the blurring of the ground made it seem as though she were about to fall... maybe that's it. Anyway, you've done a wonderful job of creating a moment seemingly suspended in time.
I love the expression on her face. She's relaxed and pleased with her mind, and surroundings. This is revealed by her expression and body posture. I loved how with this picture is somewhat faded on the rocks and partially amongst the waves. This is an astounding photo in my opinion.
