Well captured. Nice lines and separation of beach/water/sky. I think maybe one bird in the sky would have been perfect. Right now the many birds clutter and detract from the solitude of the couple. THe vignette may be a bit overpowering as well.
Nice image - the figures are a tad smaller than I'd like in relationship to the overall composition (making the birds seem nearly human-sized), and the colors aren't quite where I want them to be (seems a bit green overall) - however, it really is a lovely image all the same.
