This is a very good subject you found on the beach, very well seen! I like the soft colors on this picture aswell as the mirroring of the scene in the water.
To make this picture more interesting, more intimate I would suggest to crop it. You find my suggestion as an attachment here. I also am not shure, if the ISO setting was correct, when you took this picture, maybe it's already a strongly enlarged part of the original picture-shot.
However, I do hope you wont be angry about my critique, as I told already I like the theme you show us very much, thanks for having published this picture, thanks for shareing it in UF!
