I really loved this picture, it has such a warm and peaceful atmosphere.
I love the angle that you have used, with a cross section of both the darker part of the beach, the sunlit beach, ocean and sky. There is a lovely balance between these components. The solitary man walking into the picture perfects the composition.
Technical
Lovely lighting here, with a well controlled sunset, the highlights are not too bright. It looks like you boosted the yellow on this, which adds more warmth. Perhaps a tiny bit more contrast could have been used, especially on the sea. However, to be honest, I really like the soft colours.
My Opinion
I think that the only thing I would change about this picture would be the title. I think that "Solitude" would have been fitting and would have suited the very peaceful feeling attached with this. Maybe a nice simple border would have set it off. I really like this picture, great shot. One to be framed and put on the wall.
Very nicely done. Nice colours, and composition is perfect. It almost looks like an upside down sunset, since you have almost no sky, and the sky is reflecting on the sand. Some people will surely criticize the glare on the sand, but I think it works. I would have done it that way too.
Give me a little more sky and I'll give you a 10. Like the guy on the beach and his location in the photo. The cropping is especially good in my opinion - as much past the sun on the beach as past the man on the beach. Great job there. I would have like more sky, as much as you have land without and water on it on the left corner. Still a good photo.
