Very nicely done. One complaint is the feet seem cropped just a little too close to the edge of the frame. I don't mind the close crop of everything else. Nice touch with 2 flying birds in the background. My other complaint is the hard shadow line on his neck from his hoodie. I'm guessing you used 2 lights and maybe the one on the right needed to be higher up?
At first, I thought the blue tones took away from the image, but looking at it longer I really feel like the blue tone closely matches her expression. Couple of distractions: Only the left side of her face is in the blue tone and the railing coming in and out of focus. Will rate it 8.5 for the emotional value.
