Lovely image and great work.
My only thoughts are the fishermen and lady on bottom right hand corner. They are a little distraction for me as the image is so clean otherwise. What does it look like cropped slightly on the RH side?
Edit: Just enlarged the image on my 24" monitor and when using the bottom slider I could crop out the people. Also if you could clone out the fishing net you can still leave the walkway in which keeps interest in the photo.
All IMO, but I can inderstand if you leave them in, to not making the photo to sterile.
