Peace !
This is what I felt while shooting the shot. It's the sea in the background and the model being totally lost in and around the beach. Frankly, I didn't instruct the model to pose the way she is posing. Yet, I was waiting for her sheer expressions to come out. Once I observed the same, I took the shot !
The set up used for the shot is a 5D ( mark 3 ) canon camera along with a 40 mm ( f/ 2.8 ) Lens. Minimal post processing is used to crop and colour correct the image.
