I really like this picture for several reasons First of all there are two waves the one closest to the camera indicates the middle of the focus length and the other one farthest away makes a fine contrast between the ocean and the sky (this really helps to indicate where the horizon is in a picture where the colours cant help separate the two) Another thing i also like is how the wave closest to the camera is directly behind her shoulders, this help to create a contrast in composition where you have the straight line from the wave contrasted by the tilted line created by her shoulders. Some things that could be altered is the shadow from her head on her chest, it is a little hard but can easily be softened with a light-bouncer (used under the shoot) or altered in Photoshop with a softening brush. The last thing i would like to comment on is neither negative or positive. The hair that is beneath her chin makes a disruption of the neck and makes it seem kind of messy, but on the other hand adds a nice natural feel to the picture which makes it seem unedited. Which one of the two you are going for is up to you but if you solely look at the esthetic you should try to remove the rouge hair with photoshop or other retouch-programs. It would surely help make the picture look a whole lot better acording to my personal oppinion
Wonderfull shot which seems so catch one single moment of a simple happening. The nakedness, the curly hair pushes the impressions of airiness and this aspect is so great in here. Everything looks so natural that its nearly to perfect for showing a normal moment of live. But this is still the fact, that comes to my mind: That life could be so easy and beautyfull by enjoing it from time to time. Her smile chains my view and the dark eyes, which can not be seen easily caused by the grey colours seems to invite the watcher to feel the moment.
