Interesting - when I checked your reply last night from my phone, I agreed the crop I had posted looked very strange indeed.
However, checking again today from work, I can see my original crop doesn't have the grass stopping at the right of the frame and, like your example, you can see the sand to the right (avoiding the grass "going out of the image"). I think this means that your monitor resolution might not be quite high enough to display the entire image, the work monitor is 1280x1024 and I can see the entire image. If monitors are set to 1024x768 you won't see the whole crop.
r.e. cropping the left-most hut out, interesting example. I think it probably does improve it.
Sadly this, and all my other images posted so far, are now printed so it's too late to change them
